Introduction  
WELCOME ABOARD!  
hanks for choosing the VOX AD15VT-XL, AD30VT-XL, AD50VT-XL or AD100VT-XL  
Valvetronix amp.To ensure a long and trouble-free relationship with your new amp,  
Tplease read this manual carefully, use the amp as directed and keep the manual  
for future reference.  
MAIN FEATURES  
The XL-series uses Valve Reactor technology, and feature a power amp circuit con-  
taining a 12AX7 (ECC83) dual triode valve (“vacuum tube”) that would normally be  
used in a preamp. This allows the amp to produce the true sound and feel of a bona  
fide all valve (tube) amp.  
Sophisticated modeling technology is used to provide eleven different amps. They  
range from classic vintage amps of the past to current expensive high-end valve  
amps, and are accessible at the turn of a knob.  
Eleven high-quality effects are built in and seven are multi effects that let you use two  
effects simultaneously plus Noise Reduction.  
You can store your favorite amp and effect settings as a program, which contain two dif-  
ferent settings (CH1 and CH2).You can switch between these settings from the top  
panel, or by using the optional VFS2 foot switch connected to the rear panel (Channel  
Select mode). In addition, there’s one preset program for each amp type (Preset mode).  
In Manual mode the sound you hear will reflect the physical settings of the knobs.  
If you connect the optional VFS2 dual foot switch (sold separately), you can use it to  
switch programs or bypass effects.  
The power level control (The AD15VT-XL doesn’t have this feature.) lets you adjust the  
output wattage of the power amp. This means that even when the master volume is  
turned up to the max to drive the Valve Reactor power amp, you can adjust the volume  
without losing any tone.  
The external speaker out jack (AD50VT-XL / AD100VT-XL only) lets you connect a  
guitar speaker cabinet (8 ohm) of your choice.  
The effect send/return jacks (AD100VT-XL only) allow you to connect your external  
effect processor in a loop connection.

VALVE REACTOR TECHNOLOGY  
THE POWER (AMP) AND THE GLORY!  
alve Reactor technology was first used on the VOX AD60VT & AD120VT Val-  
vetronix amps.  
V
Since conventional modeling effects for line recording are not used directly with a  
speaker, they do not include a power amp circuit, output transformer, or speaker. In other  
words, they only have a preamp circuit.  
A real valve amp sound, however, is produced not just by the preamp, but also by the tone  
and distortion of the power amp, and by the constant changes in impedance that are cre-  
ated by the power amp driving the speakers. The XL-series contains an actual low-watt-  
age valve power amp circuit, a virtual output transformer (patent applied for) that uses  
solid-state components to simulate an output transformer, and a dummy speaker circuit  
that simulates the varying impedance of a real speaker. This means that although it’s low-  
power, the power amps used in both the XL-series has the same circuit structure of an  
actual all-valve (tube) amp.  
While much of the tone creation and shaping carried out is done in the digital  
domain, the Valve Reactor power amp is 100% analogue. The resulting journey your gui-  
tar’s signal takes through the analogue world of the power stage plays a major role in pro-  
viding the all-important feel and tone of the original amps we modelled.  
The Valve Reactor power stage is, to all intents and purposes, a bona fide valve (tube)  
push-pull power amplifier, but in miniature. It utilizes a 12AX7 (ECC83) valve (a dual tri-  
ode device — meaning “two valves in one”) and is equipped with an output transformer,  
just like a “real” valve amp.  
The power amp output signal is designed to “read” the constantly changing impedance  
curve of the dummy speaker circuit system and feed this information back to the virtual  
output transformer — just like an all valve amplifier does. This information permits the  
behavior of the valve stage to vary with the speaker load (impedance), which is another  
important part of “real world” valve tone.

Apart from the vital valve tone this ingenious power amp design provides, it also  
allows us to replicate various “circuit characteristics” that are unique to the all-valve  
power stages of the amps we’ve modelled. These “characteristics” include: Class A or  
Class AB operation, Presence and Resonance (low end) control circuitry (both found in  
the negative feedback circuit that some, but not all, valve power amps have) and power  
output. Being able to match such vital characteristics helps ensure that each and every  
one of our models is as tonally authentic as possible — as opposed to the usual “close  
but no cigar” norm of digital modeling. And just so you know, this patented in USA power  
amp technology is unique to VOX Valvetronix.  
Quick Start  
nce you’ve satisfied your primal urge to play, I’d like to urge you to give this man-  
ual a chance — it’s been written by a fellow guitar nut and this amp boasts some  
Okiller bells ‘n’ whistles that warrant your interest. In short, it’ll be worth your while,  
we promise. This said, here’s the “Quick Start” — enjoy! I look forward to taking you  
through the amp in more detail once you’re done...  
HINT: If you’re not sure of the location of a control or switch referred to in this Quick Start  
section, you can refer to the illustrations in the section entitled “The Guitarist’s Guided  
Panel Tour” (page 8).  
SETUP  
1. Turn the MASTER volume control on the amp all the way down.  
2. Plug one end of the supplied power cord into the AC power connector on  
the rear panel, and plug the other end into a wall outlet.  
3. Plug your guitar into the INPUT jack on the top panel.  
4. Turn on the POWER switch.  
5. Slowly raise the MASTER volume to adjust the volume.  
HINT: The rear panel POWER LEVEL control controls the output level of the power amp,  
letting you adjust the volume while keeping that great-sounding power-amp distortion!  
(The AD15VT-XL doesn’t have this feature.)  
NOTE:You won’t hear any sound for a few seconds while the valves warm up. This isn’t a  
malfunction, this is how a tube operates normally.

CHECKING OUT THE PRESET PROGRAMS  
1. Press the top panel PRESET button.  
The PRESET LED will light (this means you’re in Preset mode).  
2. Turn the AMP selector to select an amp type.  
For each amp type you select, a preset containing a typical sound for that type will  
be selected; i.e., the GAIN, VOLUME, TREBLE, MIDDLE, BASS, and effect set-  
tings will be switched automatically. If you want to hear the amp without effects,  
press the effect bypass button.  
SWITCHING BETWEEN THE CHANNELS OF A PROGRAM  
1. Press the top panel CH (Channel) button.  
The CH1 or CH2 LED will light, and the program assigned to the corresponding  
channel will be recalled (Channel Select mode).  
2. CH1 and CH2 will alternate each time you press the CH button.  
HINT:You can store your favorite settings in each channel of the program. For details,  
see “Storing your program” (page 17).  
CREATING YOUR OWN SOUNDS  
1. Press the top panel MANUAL button.  
The MANUAL LED will light (you’re in Manual mode).  
HINT:You can also create your own sounds in Preset mode or Channel Select mode.  
However, the process is a bit easier to understand in Manual mode, since the positions of  
all knobs (except the EDIT 1 knob) are exactly what you’re hearing. In other words, what  
you see is what you get!  
2. Use the AMP selector to select an amp, and adjust the GAIN, VOLUME,TRE-  
BLE, MIDDLE, and BASS accordingly.  
3. If you want to use an effect, use the EFFECTS selector to select an effect  
type, and use the EDIT 1 knob to adjust the depth of the effect. For modula-  
tion-type effects like CHORUS or TREMOLO, or the DELAY/REVERB effect,  
just press the TAP button twice to set the modulation speed or the delay/  
reverb time to the corresponding interval — it doesn’t get much easier than  
that!  
If you don’t want to use an effect, press the BYPASS button.You can edit more  
effect parameters but you’ll have to read the manual to find out how.  
4. When you’ve come up with a sound you like, write it as described in “Stor-  
ing your program” (page 17).

The Guitarist’s Guided Panel Tour  
In this chapter we’re going to take a look at the top and rear panels of your Valvetronix  
amp.

1. INPUT SECTION  
This is where you plug in your guitar.  
2. AMP SECTION  
Here’s where you make your settings.  
AMP selector switch  
This selects one of the amp type models. As mentioned earlier, each model repli-  
cates the preamp (with its gain and tonal response), the power amp operation  
(class A or AB), negative feedback circuitry (or lack thereof), and the response of  
the tone controls and their placement within the circuit. For details, turn to “Amp  
models and effects” (page 20).  
Preset mode (when the PRESET LED is lit) lets you select preset programs that  
contain typical sound and effect settings for each amp type.  
GAIN  
This adjusts the preamp gain. Higher settings will give you more distortion  
VOLUME  
This adjusts the volume.  
8
 
   
TREBLE, MIDDLE, and BASS  
This trio of knobs allow you to dial in the exact amount of high, mid, and low fre-  
quencies. Also, as you’d expect (and hope!), the exact manner in which each one  
of these controls behaves and also interacts with the others is dependant on the  
amp model selected. Turn to the “Amp models and effects” section (page 20) for  
more information.  
NOTE: In keeping with the originals, certain models will produce almost no sound if  
all of these three tone controls are turned all the way down (counter-clockwise).  
NOTE: Not all of the original amps that we modeled actually have all three of the Tre-  
ble, Middle, and Bass controls. In such cases, we allow you to use all three knobs to  
effectively increase the tonal range of the original. Turn to the “Amp models and  
effects” section (page 20) for more information.  
MASTER  
This adjusts the volume that is output from the preamp to the Valve Reactor power  
amp. This will vary the amount of distortion created by Valve Reactor.  
NOTE: The MASTER volume control is NOT programmable.  
NOTE: The GAIN control also affects the amount of distortion. For some settings,  
there may be virtually no distortion.  
3. EFFECT SECTION  
Here you can make settings for effects and noise reduction. For details on each effect,  
refer to “Amp models and effects” (page 20).  
EFFECTS  
Selects the type of effect.You can use the TAP button, EDIT 1 knob and Bypass  
button to adjust the parameters of each effect. When you select an effect type, the  
effect parameters will be initialized and Effect Bypass will be defeated.  
EDIT 1  
Use this to adjust the parameters of each effect. By using this knob in conjunction  
with the TAP and BYPASS buttons as described below, you can adjust three differ-  
ent parameters. (That is, if the BYPASS LED is dark.)  
Turn EDIT 1 (without pressing a button) (EDIT 1)  
Turn EDIT 1 while pressing TAP (EDIT 2)  
Turn EDIT 1 while pressing BYPASS (EDIT 3)  
If the BYPASS LED is lit (the effect is bypassed), you can hold down the TAP but-  
ton and turn the EDIT 1 knob simultaneously to adjust the noise reduction sensi-  
tivity.  
NOTE:You can’t adjust the effect parameters while the BYPASS LED is lit.  
9
 
TAP (EDIT 2) and LED  
This button enables you to set the speed of a modulation-type effect (such as  
CHORUS or FLANGER) the delay time REVERB length; simply press the button  
twice at the desired interval.  
The LED blinks at the specified speed or time.  
HINT:To set the time to exactly match the tempo of a song, press the TAP button sev-  
eral times along with the song.  
HINT:You can also adjust the speed or time, by holding down the TAP button and  
turning the EDIT 1 knob. (This is the EDIT 2 mode)  
NOTE: If the BYPASS LED is lit, you won’t be able to use the TAP switch to set the  
time. (The TAP LED will be dark.)  
BYPASS (EDIT 3) and LED  
If you don’t want to use an effect, press this button to turn the effect off (i.e.,  
bypassed). If the effect is bypassed, this LED will be lit.  
NOTE:You can’t adjust the effect parameters if the BYPASS LED is lit.  
HINT: While the effect is bypassed, you can adjust the noise reduction sensitivity by  
holding down the TAP button and turning the EDIT 1 knob.  
HINT: The bypass setting is remembered even when you switch modes, switch pro-  
grams, or turn off the power.  
HINT: The Bypass button can be used to modify effect parameters (EDIT 3). Press  
and hold Bypass and simultaneously turn the EDIT 1 knob. See the chart on page 25  
for what parameters can be controlled.  
4. PRESET/MANUAL/CHANNEL SECTION  
PRESET and LED  
This button puts your Valvetronix amp into Preset mode and you can use the AMP  
selector to select a “typical” setting for each amp type. If the PRESET LED is lit,  
you’re in Preset mode!  
MANUAL and LED  
This button puts your Valvetronix amp into Manual mode which means the physi-  
cal position of each knob (except for the EDIT 1 knob) determines exactly what  
you will hear. This means that the amp will operate just like a conventional guitar  
amp. If the MANUAL LED is lit, you’re in Manual mode.  
CH (Channel), CH1/CH2 LEDs  
This button switches between the two channels and The LED of the selected  
channel will light. In Preset or Manual mode, the CH1 and CH2 LEDs will be dark.  
If from either of these modes you then press this CH button, you’ll switch to Chan-  
nel Select mode, and the channel (1 or 2) that you selected most recently will  
become active.  
10  
 
WRITE button  
Use this button to save a new program into CH1 or CH2. Refer to “Storing your  
program” (page 17).  
5. POWER SWITCH  
When the power is on, the indicator located above the switch will be lit.

AC power  
This is where you connect the included power cord.  
FOOT SW  
You can connect the optional VFS2 dual foot switch (sold separately) here, and  
use it to switch programs or bypass the effect while you perform.  
POWER LEVEL  
This adjusts the output wattage of the power amp.  
AD30VT-XL: less than 0.1 W – 30 W AD50VT-XL: less than 0.15 W – 50 W  
AD100VT-XL: less than 0.2 W – 100 W  
NOTE: The AD15VT-XL doesn’t have this control.  
NOTE: The power level setting isn’t saved as part of the program.  
11  
 
 
This control lets you get that highly desirable, fat, warm sound of the Valvetronix  
power stage being driven hard (a common trait of all great valve power amps), at  
various levels. This will enable you to play comfortably in a small room or compro-  
mising your all-important tone.  
LINE/PHONE  
Use this jack if you’re plugging directly in to a mixer, recording device, or if you’re  
using headphones. The output from this jack is taken from immediately before the  
ValveReactor power amp, and the character of the guitar amp cabinet is applied to it.  
NOTE: Connecting headphones to this jack will mute the internal speaker.  
EXTERNAL SPEAKER OUT jack  
You can connect a guitar speaker cabinet to this jack.  
NOTE: Sound will not be output from the internal speaker if you use the  
EXTERNAL SPEAKER OUT jack.  
NOTE: The AD15VT-XL and AD30VT-XL don’t have this jack.  
Important: To ensure that your system works correctly, you must observe the follow-  
ing points.  
a) Don’t use an external speaker whose impedance is other than 8 ohms.  
b) Don’t connect a speaker whose rated input capacity is less than 50 watts (100  
watts for the AD100VT-XL). The speaker may be destroyed if you ignore this cau-  
tion — not recommended!  
c) You must use a speaker cable to connect an external speaker. Don’t use a  
shielded cable like the one you use to connect a guitar to an amp.  
d) You must turn off the power before connecting the cable. Connecting the cable  
while the power is turned on may damage your amp.  
LOOP SEND jack, RETURN jack  
These are loop jacks that you can connect to your external effect processor. Con-  
nect the SEND jack to the input of your external effect processor. Connect the  
RETURN jack to the output of your external effect processor.  
NOTE: The AD100VT has these jacks.  
12  
 
About the three operating modes  
he XL-series contains eleven “preset programs.” To select one of these, enter Pre-  
set mode (which simply means, press the PRESET button) and turn the AMP  
Tselector.  
There are also two rewritable “channel programs” which you can select by press-  
ing the CH button or by using the optional VFS2 foot switch.  
PRESET MODE (SELECTING A PRESET PROGRAM)  
In Preset mode, simply turn the AMP selector to select a preset program that contains  
“typical” settings for each amp type.The GAIN, VOLUME, TREBLE, MIDDLE, BASS, and  
effect settings will switch automatically.  
GETTING TO PRESET MODE  
If the PRESET LED is dark, you’re not in Preset mode. Press the PRESET button to  
make the PRESET LED light.  
NOTE: If the CH1 or CH2 LED is blinking (i.e., when you’re in the middle of selecting a  
writing-destination for the program) the PRESET LED won’t light when you press the  
PRESET button the first time. In this case, just press the PRESET button once again.  
SELECTING A PRESET PROGRAM  
With the PRESET LED lit, turn the AMP selector and the preset program for each amp  
type will be selected. (The physical settings of the top panel control knobs and EFFECTS  
selector are ignored at this time.)  
HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is lit,  
the effect is bypassed. Press the BYPASS button once again to cancel bypass and enable  
the effect once again. The XL-series remembers the bypass setting even if you switch  
modes or programs, or turn off the power.  
CHANNEL SELECT MODE (SELECTING A CHANNEL PROGRAM)  
In Channel Select mode you can press the CH button to recall the program saved in each  
channel (CH1 and CH2), automatically switching all of the amp and effect parameters.  
GETTING TO CHANNEL SELECT MODE  
If the CH1 and CH2 LEDs are dark, you’re not in Channel Select mode. Press the CH  
button. Either the CH1 or CH2 LED will light, and you’ll be in Channel Select mode.  
NOTE: If the CH1 or CH2 LED is blinking (i.e., when you’re in the middle of selecting a  
writing-destination for the program), the program won’t switch when you press the CH but-  
ton the first time. In this case, press the TAP button to stop the blinking.  
13  
 
     
SWITCHING CHANNELS  
With either the CH1 or CH2 LED lit, press the CH switch. The channel will change each  
time you press the button, and the program stored in each channel will be recalled. (The  
physical settings of the top panel selector knobs and control knobs are ignored at this  
time.)  
HINT: If the optional VFS2 dual foot switch is connected to the rear panel, you can  
use it to switch programs. For details, refer to “Using the VSF2 dual foot switch”  
HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED  
is lit, there is no effect.To turn the effect on, press the BYPASS button once to turn off  
the LED. The XL-series remember the bypass setting even if you switch modes or  
programs, or turn off the power.  
MANUAL MODE  
When the XL-series is in Manual mode, it works just like a non-programmable guitar amp.  
In other words, the positions of all top panel selectors and knobs (except for the EDIT 1  
knob) indicate exactly what you’re hearing.  
GETTING TO MANUAL MODE  
If the MANUAL LED is dark, you’re not in Manual mode. Press the MANUAL button; the  
MANUAL LED will light, and you’ll be in Manual mode.  
NOTE: If the CH1 or CH2 LED is blinking (i.e., when you’re in the middle of selecting a  
writing-destination for the program), the MANUAL LED won’t light when you press the  
MANUAL button the first time. In this case, simply press the MANUAL button once again.  
NOTE: In Manual mode when you edit parameters that aren’t defined by a knob setting  
(i.e., effect parameters or noise reduction settings), those settings are saved automati-  
cally, and will be recalled the next time you enter Manual mode. However if the EFFECTS  
selector is at a different position than it was when you were last in Manual mode, the  
default settings for that effect type will be loaded.  
HINT: If you want to bypass the effect, press the BYPASS button. If the BYPASS LED is  
lit, there is no effect. To turn the effect on, press the BYPASS button once to turn off the  
LED. The XL-series remembers the bypass setting even if you switch modes, programs,  
or turn off the power.

Creating and storing your own  
program  
here are two ways you can do this; by tweaking an existing preset program that’s  
close to what you have in mind, or by starting from scratch.  
T
CREATING YOUR OWN PROGRAM  
Let’s start from scratch.  
1. Choose any program in Preset or Channel Select mode, or select Manual  
mode.  
HINT: Since we’re starting from scratch it doesn’t matter what program you choose.  
2. Use the BYPASS button to bypass the effect. (The BYPASS LED is lit.) If you  
want to use an effect, you can add it at the end of this process.  
3. Use the AMP selector to select the amp you want to use.  
HINT: For details on the amp types, refer to “Amp models and effects” (page 20).  
4. Adjust the top panel GAIN, VOLUME,TREBLE, MIDDLE, and BASS knobs as  
desired.  
5. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise  
reduction.This setting is also saved as part of your program. For details,  
refer to “Adjusting the noise reduction” (page 16)  
HINT: Adjust the noise reduction so that you don’t hear noise when you’re not playing  
your guitar.  
6. If you want to use an effect, press the BYPASS switch once again to turn  
bypass off (the BYPASS LED goes dark).  
7. Select an effect, and make adjustments. For example if you want to add  
delay, turn the EFFECT selector to “DELAY.” If the selector is already set to  
“DELAY,” you’ll have to turn it to a different effect and then back to “DELAY.”  
Use the TAP button or EDIT 1 knob to adjust the delay time and delay level (the  
amount of delayed sound).  
DELAY TIME:  
Press the TAP button twice (at the desired interval), or hold  
down the TAP button and turn EDIT 1.  
DELAY LEVEL:  
Turn EDIT 1 (without pressing any button).  
DELAY FEEDBACK: Turn EDIT 1 while holding down the BYPASS button.  
15  
 
   
HINT: For details on the effects, refer to “Amp models and effects” (page 20).  
8. When you’ve come up with a sound you like, store the program.  
NOTE: In Preset or Channel Select mode, the changes you made will be lost if you  
switch to a different program or Manual mode or turn off the power without storing the  
program first.  
NOTE: The effect bypass setting isn’t stored as part of the program.  
ADJUSTING THE NOISE REDUCTION  
Here’s how to adjust the noise reduction.  
NOTE: The noise reduction setting is part of each program. In Preset and Channel  
Select modes, your setting will be lost if you switch to a different program or to Man-  
ual mode (or turn off the power) without storing your edited program first.  
1. Press the BYPASS button to make the BYPASS LED light.  
2. Hold down the TAP button and turn the EDIT 1 knob to adjust the noise  
reduction sensitivity.Turning the knob toward the right will produce greater  
noise reduction (less noise). If you turn the knob all the way to the left, noise  
reduction will be off, and won’t do anything (more noise).  
NOTE: Depending on the guitar you’re using, excessively high noise reduction set-  
tings may cause notes to be cut off in an unwanted manner!  
3. If you want to use effects, press the BYPASS button to make the BYPASS  
LED go dark and the effect(s) will be heard.  
16  
 
 
STORING YOUR PROGRAM  
When you’ve come up with a sound you like, you should store (write) the program.  
1. Press the WRITE button.The CH1 or CH2 LED will blink.  
2. Press the CH button to select the channel in which you want to store your  
program.The program will be stored in the channel whose indicator is blink-  
ing.  
HINT: If, during this process, you decide that you really don’t want to store the pro-  
gram, you can press the TAP button to cancel at this point.The LED will stop blinking,  
and you’ll return to the mode in which you were.  
3. Press the WRITE button once again.Your program will be saved in the spec-  
ified channel, and the LED of the destination channel will stop blinking and  
remain lit.  
NOTE: The program that was previously stored in that channel will be overwritten; in  
other words, the settings that used to be stored in the channel you selected in step 2  
will be erased.  
NOTE: The effect bypass setting isn’t stored as part of the program.  
NOTE: If you’re creating your sound in Preset or Channel Select mode, your changes  
will disappear if you switch to a different program or to Manual mode before storing.  
CHECKING THE SETTINGS OF A PROGRAM (ORIGINAL VALUES)  
If you want to find out exactly what settings are saved in a preset or user program, you  
can use the Original Value function.  
When you’re turning a knob to adjust the value of a parameter, and the value at that  
moment matches the value that is saved in the program (i.e., the “original value”), the  
PRESET LED will blink if you’re in Preset mode, or the channel LED will blink if you’re in  
Channel Select mode.  
HINT: When you’ve found a program you like, and want to know just what settings it  
contains, simply use this Original Value function!  
NOTE: Since the top panel MASTER volume, the rear panel POWER LEVEL control  
are not programmed, the original value display will not occur for these settings. Also,  
the Original Value function doesn’t operate in manual mode.  
17  
 
   
RESTORING THE FACTORY SETTINGS  
Here’s how you can restore the factory settings.  
NOTE: If you do this, the programs you saved in the channels will be completely erased,  
and will be reset to the factory settings.  
NOTE: Effect and noise reduction settings made in the Manual mode will also be erased.  
1. Turn the power off.  
2. While holding down both the CH and WRITE buttons, turn the power on.  
When the CH1 and CH2 LEDs begin blinking, release these two buttons.  
HINT: If you decide to abort this operation, press the TAP switch at this point.  
3. When you press the WRITE switch, the CH1 and CH2 LEDs will change from  
blinking to lit. Initialization will be completed in a few seconds, and the amp  
will switch to Preset mode.  
NOTE: Never turn off the power while initialization is taking place.  
18  
 
 
Using the VFS2 dual foot switch  
f the optional VFS2 dual foot switch (sold separately) is connected to the rear panel  
FOOT SW jack, you can use it to switch programs or turn effect bypass on/off.  
I
VFS2 left switch (switch 1): Switches channel programs  
VFS2 right switch (switch 2): Switches bypass on/off, or turn  
Manual mode on  
SWITCHING THE CHANNEL PROGRAM (SWITCH 1)  
Each time you press the VFS2’s left switch (switch 1), you’ll alternate between CH1 and  
CH2.  
NOTE: Switch 1 has the same function as the channel select switch on the top panel. If  
you press switch 1 in Preset mode or Manual mode, you’ll change over to Channel Select  
mode. Also, pressing switch 1 during the process of storing a program (the CH1 or CH2  
LED is blinking) will change the store-destination.  
TURNING EFFECT BYPASS ON/OFF (SWITCH 2)  
Hold down the top panel BYPASS switch and press the VFS2’s right switch (switch 2).  
This assigns the function of switch 2 as “bypass on/off.Now when you press switch 2,  
effect bypass will alternately be turned on/off.  
HINT: The amp will remember the switch 2 assignment. This setting is remembered even  
if you switch modes or programs, or turn off the power.  
SWITCHING TO MANUAL MODE (SWITCH 2)  
Hold down the top panel MANUAL switch and press the VFS2’s right switch (switch 2).  
This assigns the function of switch 2 as “Manual mode.Now when you press switch 2,  
the amp will switch to Manual mode.  
HINT: The amp will remember the switch 2 assignment. This setting is remembered even  
if you switch modes or programs, or turn off the power.

Amp models and effects  
In this section we’re going to talk about the eleven amp models and effects.  
XL AMP MODELS  
For the XL range of amplifiers, we wanted to design an amp with a selection of sounds  
that would span the entire range of heavy music. We already had a truckload of great  
amp models from the acclaimed "VT" or "Chrome" series, so we set to work brainstorm-  
ing ways that we could modify these sounds for the heavy player, at times throwing out  
the rule book entirely. We found ourselves asking things like "What would this British  
head sound like if it were Class A rather than Class AB? What if we gave a California-  
style EQ to a Bristish amp or vice versa? The results are some of the hottest hard rock  
and metal sounds we've designed to date. And all of them are based on some of the  
most legendary amps in history. So plug in an turn up. Extreme lead awaits!  
CONTROLLING FACTORS  
As already touched on in this manual “Guitarist’s Guide” although the top panel of your  
Valvetronix amp houses controls for TREBLE, MIDDLE, BASS, GAIN, VOLUME, and  
MASTER, not all of the amps we’ve modeled have as many controls. In such cases,  
rather than leave you with knobs that do nothing, we’ve made full use of all five Val-  
vetronix amp controls without compromising the accuracy of any of our models. This  
means you’ll be able to mimic the full tonal spectrum of each and every one of the origi-  
nals we’ve modeled ... and then some, thanks to the extra flexibility and additional control  
the five Valvetronix amp controls give you.  
For example, if an original doesn’t have a Gain Control (FUNCKED, CRUNCHED,  
BUZZSAW), the Valvetronix’s GAIN control will mimic the original’s Volume control. This,  
of course leaves you with three volume controls to use; VOLUME, GAIN, and MASTER.  
As you already know, MASTER is a universal, non-programmable control that allows you  
to set the overall volume of the amp. So, the programmable VOLUME control (the knob  
right next to GAIN) effectively acts as a second “Master Volume,allowing you to ensure  
that the volume of each of your programs compliments the rest. Cool stuff, I’m sure you’ll  
agree ...  
Also, if an original amp doesn’t have a complete 3 band EQ network then we’ll set  
up the “missing” tone controls on our model to be “neutral” (i.e. as the original) when set  
at 12 o’clock — thus giving you extra tonal flexibility in those EQ areas, if you so wish.  
Just so you know, the amps we modeled that don’t have individual controls for Treble,  
Middle and Bass are:

CRUNCHED (AC30TB)

TUBE TALK  
Us Brits call ’em valves while our US cousins call ’em tubes ... as the saying goes:  
England and America are merely two countries divided by a common language! Anyway,  
call ’em what you will, these wondrous glass bottles lie at the tonal heart of each of our  
11 models. As all the amps we’ve modeled hail from one of the two countries just men-  
tioned, in honor of their heritage, the descriptions of all English amps will employ the  
words “valve” and “valves,while the American ones will be tubular!  
QUESTION: What’s the difference between an ECC83 preamp  
valve and a 12AX7 preamp tube?  
ANSWER: Nothing! They’re the same exact thing — namely the  
most popular preamp tube in ampland. ECC83 is the British name,  
12AX7 (a.k.a. 7025) is the American.  
POWER AMP ACCURACY  
As already touched on a couple of times, what happens in the power stage of any good  
tube amp is of paramount importance to the way the amp sounds, feels and behaves.  
The way the power amp operates (Class A or Class AB), the power tubes used  
(EL84s,EL34s, 6L6s), the exact nature of the negative feedback loop circuitry, and how  
the power stage interacts (a relationship called damping) with the speaker(s) it is driving  
— all these things play a vital role in the creation of tone. And, thanks to our patented in  
USA Valve Reactor Technology all these important bases are faithfully and accurately  
covered. For example: if you choose the amp model CRUNCHED — an amp with a Class  
A power stage and no negative feedback — that’s exactly what your Valve Reactor power  
amp reconfigures itself to emulate. And, as an added bonus, thanks to our rear panel  
POWER LEVEL control you can adjust the output power (Wattage) to best suit the size of  
the room you’re playing in. (The AD15VT-XL doesn’t have this feature.)  
TURN IT UP!  
Truly great, all-valve amps have one thing in common — they invariably sound at their  
best when they’re cranked to the max! It’s got nothing to do with eardrum shattering deci-  
bels either; it’s just that when the power valves are driven hard, they definitely impart a  
unique tone and width to the overall sound. Thanks to the awesome accuracy of our  
Valve Reactor power amp, the same is also true of your Valvetronix combo. For this rea-  
son, we heartily recommend that you crank the sucker up as often as possible. And, as  
already pointed out, thanks to our unique POWER LEVEL control (not provided on the  
AD15VT-XL), you can adjust the output Wattage to suit every occasion — from bedroom,  
to garage, to gig ... and all points in-between. So, what are you waiting for — select, crank  
‘and’ enjoy!  
This all said, let’s take a look at each of our amp models...  
21  
 
GLASS  
For this amp type, we modeled the Clean channel of a very rare, very expensive  
and respected 100 Watt head named the Overdrive Special. We auditioned sev-  
eral top-shelf boutique amps for this model but this amp was the clear winner. Its  
beautifully rounded low-end, delightfully transient mid-range attack and sweet tre-  
ble make it the perfect clean sound to complement the high gain destruction that  
will ensue further down this sound list.  
Original’s tube compliment: 3 x 12AX7s in preamp, 4 x 6L6s in power amp.  
FUNKED  
This dual channel, black-faced beauty is considered a “must- have” 2x12 combo  
for many professionals. Its celebrated clean sound is very tight “n” twangy, with a  
deep, taut, piano-like bass. This hot-rodded clean sound was inspired by the  
glassy clean sounds used by a famous funk metal band. In keeping with the origi-  
nal, when pushed hard the bass tends to crumble so raise the MIDDLE and lower  
the BASS. Because the EQ network of the FUNKED model lies before the main  
gain stage of its preamp, pushing the mids results in a singing clean tone.  
Original’s tube compliment: 4 x 12AX7s & 2 x 12AT7 (a.k.a. ECC81) in preamp,  
4 x 6L6s in power amp.  
BUZZSAW  
Fire up the BUZZSAW! This sound was inspired by the pioneering sounds of '70s  
hard rock and metal. Based on a British-made 50-watt head, this sound churns  
out a dark, grinding tone perfect for any aspiring prince of darkness! To create this  
sound, we started with the “High Treble” channel of a 1971, 50 Watt, four input, all-  
valve head then we cranked the gain and boosted all bands of the original's EQ.  
As this amp has no master volume facility, the way to use it to its full potential is to  
crank the Volume. To achieve the same response as the original, turn the VOL-  
UME to maximum and use the Master Volume to set your desired volume level.  
Wind the GAIN control all the way up and immerse yourself in an instantly recog-  
nizable, organic, driving overdrive.  
Original’s valve compliment: 3 x ECC83s in preamp, 2 x EL34s in power amp.  
CRUNCHED  
This sound is based on a very rare modded VOX AC30/6TBX Top Boost combo  
and adds hot-rodded gain levels and a completely twisted EQ to deliver deep,  
crunchy guitar tones. GAIN, TREBLE and BASS mimic the original’s Volume, Tre-  
ble and Bass controls.  
The MIDDLE is an “extra” with 12 o’clock being its “neutral” position.  
Our CRUNCHED AC30TB model produces rich overdrives that have a glorious, throaty  
bark -just like those classic, “Class A” tones that have made the original a “must have”  
in any serious player’s amp collection but taken to a whole new level in the XL range!  
22  
 
Original’s valve compliment: 5 x ECC83s & 1 x ECC82 in preamp, 1 x GZ34  
rectifier, 4 x EL84s in power amp.  
THRASHED  
This is modeled on a 1983, all tube, single channel 100 Watt head that boasts a  
Master Volume control - a wonderful feature that allows the user to dial in a great  
crunch tone without having to max out the amp’s volume. Invariably played with its  
Gain control cranked to the max, this amp was responsible for the fat, roaring  
sound that dominated ’80s hard rock and heavy metal. In the 80’s this amp was  
the only amp of choice...and, for many, still is!  
Although UK ’80s amp on which THRASED is based was famous for its distinctive,  
cranium-crushing crunch, when you roll back your guitar’s volume knob you’ll get  
a bright, clean sound that will cut through any mix like a hot knife through butter.  
For the XL range, we modded our original UK 80s model adding tons of gain, and  
scooping the EQ for complete THRASHED destruction!  
Original’s valve compliment: 3 x ECC83s in preamp, 4 x EL34s in power amp.  
RAGED  
This sound really needs no introduction! We started with our "UK Modern" model  
which is modeled on the High Gain channel of a modern, all-tube 100 Watter. It  
combines a toneful high gain preamp stage with the unmistakable, “snarling”  
punch and girth the UK ’80s power stage offers. The result is a highly aggressive,  
tone-breathing monster capable of mondo gain while retaining individual note def-  
inition. But that wasn't enough for the XL range. We wanted it to breathe fire! So  
we added some mods to the original sound like boosted bass and mid frequen-  
cies, and we--of course--turned up the gain.With the GAIN control on full, RAGED  
allows lead lines to soar into soulful feedback, while its low-end “chunk” remains  
tight and punchy. Wimps beware!  
Original’s valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.  
MODERN  
This model is an even HIGHER gain modification to the “Modern High Gain” chan-  
nel of a brutal, 100 Watt, armour-plated beast. Its deep low-end, somewhat “fizzy”  
top and Monster-like gain has made this amp a mainstay for many modern, metal  
acts who either tune their guitars down low, or wield 7 -string axes. We scooped  
the EQ so much we needed a bulldozer and, yes, we added more gain. Much  
more. The result is devastating.  
If you play slamming, “nu-metal” that’s tuned low, then MODERN could well be the  
only way to go!  
Original’s tube compliment: 5 x 12AX7s in preamp, 2 x 5U4G rectifier tubes, 4 x  
6L6s in power amp.  
23  
 
FLUID  
If fast, legato licks and thick saturated chunking is your thing, look no further.  
Again, we started with our "UK Modern" model which is modeled on the High Gain  
channel of a modern, all-tube 100 Watter. But this time we modded the mid-range  
EQ to emphasize the almost vocal-like midrange favored by certain legato style  
players known for using headless guitars and playing VERY fast. Of course, this  
being the XL range, we dimed out the gain to the absolute max. Plug in and fly!  
Original’s valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.  
MOLTEN  
This is modeled on the Overdrive Channel of an all-tube, 100 Watt head built in  
1991 and covered in snakeskin! Last time around, we called this US HIGAIN but  
our modded MOLTEN sound is capable of even more powerful, heavily saturated  
sounds that combine an open low-end with compressed mids and highs. The  
result is a tone that remains focused and well defined at even the most extreme  
gain settings. Plug in and take cover!  
NOTE: The Molten preset features our Octave effect. When the Octave effect is on,  
we do not recommend playing chords unless you are going for an unusual effect!  
Original’s tube compliment: 4 x 12AX7s in preamp, 4 x 6L6s in power amp.  
BLACK  
This sound was created when we were having some fun mutating our UK Modern  
model. We wondered what this famous UK-made 100-watt hi-gain amp would  
sound like if it operated in Class A, rather than Class AB. With this modification,  
BLACK was born! Like the other XL sounds, it's tailor-made for hi-gain shred, and  
it's a totally unique sound you can only find in the XL range!  
Original’s valve compliment: 4 x ECC83s in preamp, 4 x EL34s in power amp.  
DAMAGED  
For the DAMAGED sound, we started with a US HI GAIN model and then pretty  
much tossed out the rule book in our quest for gain. Not only did we crank the gain  
to searing levels, but we completely re-voiced and modified the EQ of the original  
model. DAMAGED is a thick, dark ultra hi-gain sound. Warn your neighbors and  
get ready to shred!  
Original’s tube compliment: 4 x 12AX7s in preamp, 4 x 6L6s in power amp.

EFFECTS  
The XL-series provides eleven of the most popular effects (some effects actually com-  
bine two effects). you can adjust the SPEED parameter of modulation effects or the TIME  
parameter of delay/reverb effects simply by pressing the TAP switch twice. In addition to  
using the EDIT 1 knob to adjust the most important parameters, you can make more  
detailed adjustments by holding down the TAP button or BYPASS button while turning the  
EDIT 1 knob.

NOTE: In order to adjust the effect parameters, Effect Bypass must be off (BYPASS LED  
dark). If you hold down the TAP switch and turn the EDIT 1 knob when bypass is on  
(BYPASS LED lit), you’ll be adjusting the noise reduction — not the effect parameter.  
HINT: If don’t want to use an effect in a channel program, select either DELAY or  
REVERB as the effect type, and turn the EDIT 1 knob all the way to the left. This will set  
the DELAY LEVEL or REVERB LEVEL to the minimum setting.  
OCTAVE  
This effect generates a note one octaves lower than the one you're playing, adding thick-  
ness and "weight" to single note lines.  
EDIT1  
“MIX”  
Adjusts the mix level of the note one octave below.  
HINT:Like all pedals of this type, OCTAVE only works with single notes...chords confuse  
the heck out of it! NOT a fault - that's just the way these pedals operate.  
25  
 
 
COMP  
Want to play a clean passage that needs to be nice, smooth, and even? Need a bit more  
sustain on a lead line? Then look no further; COMP is the effect for you. It’s modeled on a  
compressor pedal that is hugely popular due to the percussive clean sound it can pro-  
duce — making it perfect for ’80s and ’90s pop and funk rhythm work. It can also add a  
singing, mellow, sustain to lead lines — clean or dirty.  
EDIT1  
“SENS”  
Adjusts the sensitivity of the compressor. Turning  
the knob toward the right will increase the amount of  
compression and sustain. If you turn the knob all the  
way to the left, the effect is OFF.  
EDIT2  
ATTACK”  
Adjusts the strength of the attack.  
[TAP+EDIT 1]  
HINT: In the COMP+PHASER and COMP+CHORUS combination effects, the ATTACK  
parameter is already set to the optimal value.

By adjusting this parameter you can make the rota-  
tional speed change automatically in response to the  
volume of your guitar. If you use this function, set the  
SPEED to a slow setting.  
27  
 
DELAY  
This is a model of one of the most respected analogue tape echo machines ever made.  
In the original the “echo” is produced by a playback head and the exact “delay time” is set  
by varying the motor speed. Many professionals prefer these “lo-fi” units because of the  
warm, dark echoes they produce.  
TAP  
“TIME”  
“MIX”  
Sets the delay time in a range of 1...1486 [ms].

“FEEDBACK” Adjusts the amount of feedback.  
[BYPASS+EDIT 1]  
HINT: In the CHORUS+DELAY combination effect, the FEEDBACK parameter is already  
set to the optimal value.  
WARNING! If you crank up the FEEDBACK too much, an uncontrollable, cascading “run-  
away” of echoes will occur. So, use your ears and your common sense when setting this!  
REVERB  
A model of the most popular spring reverb system used in guitar amps.

Troubleshooting  
1.The amp isn’t powering up when the POWER switch is ON.  
Is the power cable plugged into the AC power connector on the rear panel of the  
amp?  
Is the power cable plugged into an AC outlet?  
Is the AC outlet switched on and actually working?  
Does the power cable work?  
2. There’s no sound coming from the amp  
Is your guitar turned up?  
Are both ends of your guitar cable plugged into where they should be?  
Is your guitar cable working?  
Is the top panel MASTER volume turned up?  
Do you have headphones or anything else plugged into the amp’s rear panel  
LINE/PHONE jack? If “yes,unplug!  
(If you’re using the AD50VT-XL/AD100VT-XL) Could a cable be connected to the  
rear panel [EXTERNAL SPEAKER OUT] jack?  
Disconnect this jack if you’re not using an external speaker.  
If you don’t hear sound from a connected external speaker, make sure that your  
speaker cable and external speaker are not broken or malfunctioning.  
Check the settings of the GAIN, VOLUME, TREBLE, MIDDLE and BASS. On cer-  
tain amp types, if the TREBLE, MIDDLE, and BASS controls are all turned down,  
there will be little or no sound coming from the amp due to the way the circuit of  
the original works.  
If you’re in Manual mode (the MANUAL LED lit), turn the following controls above  
their minimum setting: GAIN, VOLUME, TREBLE, MIDDLE, and BASS.  
(AD100VT-XL users) Could a cable be connected to only the LOOP [RETURN]  
jack of the rear panel?  
Connect the cable from the LOOP [SEND] jack to your external effect unit, and  
connect the output of that effect unit to the LOOP [RETURN] jack.  
Adjust the output level of your external effect unit to an appropriate volume.  
3. The amp doesn’t seem very loud  
Is your guitar turned up?  
Is the amp’s MASTER volume turned down low?  
(If you’re using the AD30VT-XL/AD50VT-XL/AD100VT-XL) Is the POWER LEVEL  
knob on the rear panel turned down?  
29  
 
   
Check the settings of the GAIN, VOLUME, TREBLE, MIDDLE, and BASS con-  
trols. On certain amp types, if the TREBLE, MIDDLE, and BASS controls are all  
turned down, there will be little or no sound coming from the amp due to the way  
the circuit of the original works.  
If you’re in Manual mode (the MANUAL LED lit), turn the following controls above  
their minimum setting: GAIN, VOLUME, TREBLE, MIDDLE, and BASS.  
4. There’s no sound heard from the LINE/PHONE jack when you use it.  
Check that the top panel MASTER volume isn’t turned all the way down.  
Make sure sound is coming from the amp. IMPORTANT NOTE:You’ll need to  
unplug your headphones or cable from the LINE/PHONE jack to do this, since  
plugging something into this jack automatically mutes the amp’s speakers. If  
there’s still no sound from the amp, go to page 29 “There’s no sound coming from  
the amp.If you do hear sound, check the headphones or cable you are hooking  
up to this jack.  
5. You can’t hear any effects.  
Check that the BYPASS LED isn’t lit. If it is lit, the effect is bypassed. Press the  
BYPASS button to disengage it; the BYPASS LED will go off.  
Is the EDIT 1 knob turned down too low? Adjust the EDIT 1 knob.
