“A Guitarist’s Guide”
ongratulations on buying the VC-4 Foot Controller – a pedal board dedicated to control-
C
ling the AD60VT and AD120VT VOX
Valvetronix combos. As you are about to discover,
this incredibly useful controller has three modes
(PROGRAM SELECT MODE, INDIVIDUAL MODE
(FX on/off) and TUNER MODE) that enable you to
do a whole bunch of cool things with your feet,
including the following:
✓
Change Programs
✓
Control the amp’s volume
✓
WAH
✓
Control the speed of the U-VIBE pedal model
✓
Control the speed of any MODULATION effect
being used
✓
Tune your axe (including “silent tuning” if you
wish)
✓
Change the Tempo of the DELAY being used
✓
Switch the PEDAL, MODULATION, DELAY and
REVERB effects on/off (when the VC-4 is in
INDIVIDUAL MODE)

ETTING HOOKED UP
Hooking up your new VC-4 Foot Controller to your
Valvetronix combo really couldn’t be any easier.
Simply take the supplied cable and connect one
end to the VOX BUS input jack located on the rear
panel of the VC-4 (see below)…
VC-4
INSERT ONE END OF CABLE HERE!
In addition to being self-locking at both ends, this 5meter (16’ 4”) cable also supplies power to the VC4 directly from the amp – meaning that no annoying
power supply is needed!
A
DDING AN EXTERNAL VOLUME CON-
TROL
As you can see from the picture of the VC-4’s rear
panel, you can hook up an external Volume control
to it if you’d like. We recommend the optional V850
volume pedal but any volume pedal will suffice.
Doing this obviously adds further to the already
impressive flexibility of the VC-4 and will automatically set the VC-4’s built-in pedal to Expression
mode.
ARE
C
Although your VC-4 Foot Controller is a sturdy
beast that has been specifically designed for you to
stomp on, it should be treated with respect. Here
are a few “care and feeding” rules that we recommend you follow:
➢
Never pick up or move your VC-4 around by
grabbing hold of the built-in pedal. Always grab
hold of its main body.
➢
When transporting the VC-4, always disconnect
the cable and also the optional external Volume
Pedal, should you be using one.
➢
Only clean your VC-4 with a damp, soft cloth –
like a guitar cleaning cloth for example. NEVER
use a wet cloth though, only a damp one.
ABLE SPECS
C
If you should lose or damage the supplied cord, we
recommend you purchase a replacement from your
authorized VOX dealer. If however, this is not possible, you can use a similar length (5 meter) 10 BaseT cable…providing it is cable can be purchased
from most good computer stores.
& F
EEDING
…and connect the other end of it to the FOOT
CONTROLLER jack found on the rear panel of your
combo (see below)
AD60VT
INSERT OTHER END HERE!
WARNING! WARNING!
Base-T cable used MUST be “straight” and
NOT “cross” (how the two male connectors
are wired relative to each other). If a “cross”
cable is used, you will DAMAGE your amp
and void your warranty. So, if you do use a 10
Base-t cable other than the one supplied,
please ensure it is a “straight” one. IF IN
DOUBT, DO NOT USE!! Geddit!?

1. If you tap a tempo on it with your foot it will
change the tempo of the DELAY effect being

being used, of course!
2. If you hold down this switch for more than one
second it will switch the built-in PEDAL between
VOLUME and EXPRESSION modes. How do
you know which one has been selected? Easy,
the EXPRESSION LED (5) tells all! If it’s “on”
EXPRESSION is chosen, if its “off” then the
PEDAL will work as a VOLUME control.
5. E
When this LED is “on” it means that the BUILT-IN
PEDAL will function as an EXPRESSION pedal.
When it is “off” it means the pedal is assigned to
control VOLUME.
6. B
This pedal can be used as either a VOLUME
PEDAL or as an EXPRESSION PEDAL – it’s totally
up to you. As just mentioned, when the EXPRESSION LED is “on” it tells you that the pedal is in
EXPRESSION mode, when this LED is “off” the
pedal is working as a VOLUME controller. As also
just mentioned, to switch the pedal’s function
between EXPRESSION and VOLUME you merely
have to hold down the TAP TEMPO SWITCH (4) for
longer than a second.

OW TO USE YOUR
C
ONTROLLER
s already stated, thanks to it three distinct
operational modes (PROGRAM SELECT
A
MODE, INDIVIDUAL MODE and TUNER
MODE), your new
VC-4 allows you to do a bunch of neat things when
it is hooked up to your Valvetronix amp. These
include changing programs, turning individual FX
on and off, controlling various effects, controlling
the amp’s volume, changing delay times and tuning
your axe. We’re gonna learn how it does all this
stuff by looking at the VC-4’s three modes…..
1. P
ROGRAM SELECT MODE
As already mentioned, when your VC-4 is in
PROGRAM SELECT MODE its BANK DISPLAY
will show a Bank number. And as you’d expect,
this number will match the one in the BANK DISPLAY of the amp…duh! So, take a look at the
BANK DISPLAY and see what’s up. If it shows a
Bank number and it isn’t flashing, your VC-4 is
already in PROGRAM SELECT MODE. Let’s
assume it isn’t and suss out how to get there…
G
ETTING TO PROGRAM SELECT MODE
So, your BANK Display is displaying “ ”, “ ”,
“ ”, “ ” or is flashing, and you wanna be in PROGRAM SELECT MODE, huh? Well, to get there is a
piece of cake – all you do is one or two of the following:
1. If the BANK DISPLAY is showing “ ” it means
that the amp is in MANUAL MODE (see “The
Guitarist’s Guide” that came with your combo).
As already stated, the only way to get out of
MANUAL MODE is via the amp. To do so, simply
press either the ▲ (UP) or ▼ (DOWN) button on
the amp’s Top Panel and both the amp and the
VC-4 will revert to PROGRAM SELECT MODE.
2. If the BANK DISPLAY is showing either “ ” or
“ ” it means it is in TUNER MODE. To get out
of it, simply step on the TAP TEMPO switch. This
will return the VC-4 to either PROGRAM
SELECT MODE or INDIVIDUAL MODE. If it
goes to PROGRAM SELECT MODE (i.e. the
BANK DISPLAY shows a Bank number) you’re
ready to roll, if it doesn’t then read on…

switch and it’ll revert to PROGRAM SELECT
MODE.
4. If the BANK DISPLAY is flashing, it means you’re
halfway through changing banks. To get out of
this and get back to PROGRAM SELECT
MODE, all you have to do is press the FX ON &
OFF/CHANNEL switch.
Right, now we’ve got our VC-4 Foot Controller in
PROGRAM SELECT MODE, let’s get into how
we can change programs by merely stamping
our feet….
IMPORTANT NOTE:
PROGRAM SELECT MODE you can use
both the TAP TEMPO SWITCH and the
BUILT-IN PEDAL as already described.

HANGING CHANNELS WITHIN THE SAME

...
This is stupidly easy! As you know, the 32 programs your Valvetronix can remember are stored
in 8 Banks and each Bank consists of 4 Channels. Let’s assume for a second that the program
currently being used is 3-1. To switch to program
3-2, 3-3 or 3-4 from 3-1 using the VC-4 is incredibly simple – all you do is step on the appropriate
CHANNEL BUTTON!!
For example, say you’re currently on program 24 and you want to switch to program 2-2. All you
do is step on the CHANNEL 2 button on your
VC-4 and you’re there! Geddit!? Told you it was
“stupidly simple!”
ii) C
HANGING BANKS
This is not quite as simple as changing channels
but is still a breeze. Before we get into “how”
though, an important announcement…
IMPORTANT PROGRAM CHANGING
NOTE:
When using the VC-4 Foot Controller
you can only change between the 16 programs stored in Banks 1 – 4 or the 16 stored
in Banks 1. – 4.. This means you can’t use the
Foot Controller to change from program 2-1 to
program 3.-4, or from 1.-3 to 4-1 for instance.
The only way you can get your VC-4 from
Banks 1 – 4 to Banks 1. – 4. , or vice versa, is
via the Top Panel of the amp.
This said, let’s learn how to CHANGE BANKS
using our VC-4. We’re going to do this by following an example. So, let’s say we want to go from
program 1-1 to 4-3 using our VC-4. Here’s the
simple three-step process…

As already mentioned, when your VC-4 is in INDIVIDUAL MODE it allows you to use SWITCHES 1 –

REVERB sections of your Valvetronix amp on/off
within the program you’re using. When your VC-4 is
in INDIVIDUAL MODE “ ” shows in the DISPLAY
WINDOW.
If “ ” is in the VC-4’s BANK DISPLAY then your
Foot Controller is already in PROGRAM SELECT
MODE. Let’s assume it isn’t and work out how to
get there…
Yes sir, you’re not seeing things – this is
STEP 0! Why? Because we’ve got to get
our amp on program 1-1 before we can
start, that’s why! So let’s get it to program
1-1 by the simplest way possible – by calling the sucker up using the amp’s Top
Panel controls! And if you don’t know how
to do this shame on you! What are you
doing messing around with the VC-4 when
you don’t know how to use your amp yet?
It’s all in “the Guitarist’s Guide” that came
with your Valvetronix combo so get learning!
Right now we’re on program 1-1, we can
begin…
Press down the FX ON & OFF/CHANNEL
switch for more than 1 second. Doing this
will cause the “1” in the BANK DISPLAY to
start blinking. This means we’re ready to
select the bank we want to change to
which is Bank 4 in this instance.
To select Bank 4 merely step on SWITCH
4 on your VC-4. This will cause the Bank
display to change to “4” and start flashing
even faster. This means it is now ready for
you to select the channel you want, which
is 3…
To select Channel 3 merely step on
SWITCH 3.
There isn’t one! Congratulations, you’ve
successfully switched from program 1-1 to
4-3 as your VC-4 will attest – “4” will be
glowing (but not flashing!) brightly in the
BANK DISPLAY and the LED above
SWITCH 3 will be lit up too. Told, you it
was a simple three step process…
NDIVIDUAL MODE
(FX ON/
OFF
)
GETTING TO INDIVIDUAL MODE
So, your BANK Display is displaying a bank number (1-4 or 1.-4.), “ ”, “ ”, “ ” or is flashing and
you want to get it in INDIVIDUAL MODE? Don’t
fret, all you do is one or two of the following easy
things:
1. If the BANK DISPLAY is showing either “ ” or
“ ” it means it is in TUNER MODE. To get out
of it, simply step on the TAP TEMPO switch. This
will return the VC-4 to either INDIVIDUAL MODE
or PROGRAM SELECT MODE. If it goes to
INDIVIDUAL MODE (i.e. the BANK DISPLAY
shows “ ”) you’re ready to roll, if it doesn’t then
read on…
2. If the BANK DISPLAY is showing bank number
(1-4 or 1.-4.) it means that your VC-4 is in PROGRAM SELECT MODE. So, all you have to do is
hit the FX ON & OFF/CHANNEL switch and it’ll
revert to INDIVIDUAL MODE.
3. If the BANK DISPLAY is flashing, it means
you’re halfway through changing banks. To get
out of this and get back to PROGRAM SELECT
MODE all you have to do is press the FX ON &
OFF/CHANNEL switch. Then to get to INDIVIDUAL MODE merely hit the switch again.
4. If the BANK DISPLAY is showing “ ” it means it
is in MANUAL MODE. As already stated, the
only way to get out of MANUAL MODE is via the
amp. To do so, simply press either the ▲ (UP) or
▼ (DOWN) button on the amp’s Top Panel and
both the amp and the VC-4 will revert to PROGRAM SELECT MODE. Then hit the FX ON &
OFF/CHANNEL switch and you’re in INDIVIDUAL MODE.
Now we’ve got our VC-4 Foot Controller in INDIVIDUAL MODE we can use SWITCHES 1-4 to
turn whatever PEDAL, MODULATION, DELAY
and REVERB effects the program being used
contains. To be specific:
SWITCH 1 Switches the PEDAL SECTION on and off
SWITCH 2 Switches the MODULATION SECTION on
and off
SWITCH 3 Switches the DELAY SECTION on and off
SWITCH 4 Switches the REVERB SECTION on and
off
And as you’d hope/expect (delete as you deem
fit!), the relevant LEDs will light up when a section is “turned on” and go off when a section is
“turned off.”

IMPORTANT NOTE 1: If you forget what program you’re using, merely take a look at the
Top Panel of your Valvetronix amp and the
BANK DISPLAY and CHANNEL LEDs will

TAP TEMPO SWITCH and the BUILT-IN
PEDAL as described earlier in this guide.
COOL VC-4 FUNCTION ALERT!
CHANGING PROGRAMS IN INDIVIDUAL
M
ODE
Yes, you can do this using your VC-4 Foot Controller – how great is that!? And to do this all you
have to do is follow the exact same 3 steps you
follow when changing programs in PROGRAM
SELECT MODE. Namely:
STEP 1:Hold down the FX ON & OFF/CHANNEL
SWITCH for more than 1 second so that
the BANK DISPLAY starts flashing.
STEP 2:Select the Bank you want with
SWITCHES 1 – 4. This will cause the
BANK DISPLAY to flash faster.
STEP 3:Select the Channel you want with
SWITCHES 1 – 4. Once you’ve done
this, the BANK DISPLAY will display the
selected Bank and the LED of the
selected Channel (1 – 4) will light up for
approximately one second and then the
VC-4 will revert back to INDIVIDUAL
MODE.
NOTE 1: Remember, the Top Panel of your amp
will let you know what program you’re using when
in INDIVIDUAL MODE.
NOTE 2: As was the case when changing programs in PROGRAM SELECT MODE, you can
only change between programs stored in Banks 1
– 4 or programs stored in Banks 1. – 4., it
depends whether you are in Banks 1 – 4 or
Banks 1. – 4.. This means you can’t change from
say 1-3 to 2. (or vice-versa) using your VC-4
when in INDIVIDUAL MODE.
3. TUNER MODE
As you know your Valvetronix amp has a built-in
tuner and guess what? You can now do the same
exact thing using your VC-4 Foot Controller –
including that super cool SILENT TUNING thing
which is a must when playing live. As you’d expect,
when the VC-4 is in TUNER MODE or SILENT
TUNING MODE the note name appears in the
BANK DISPLAY while the 5 LEDs above
SWITCHES 1-4 and the TAP TEMPO SWITCH act
as your “tuner needle,” with LED 3 being the “you’re
exactly in tune” one. So, when the VC-4 is in
TUNER MODE, the note you are playing is exactly
in tune with the one shown in the BANK DISPLAY
when only LED 3 is “on.” If either LED 1 or 2 are “on”
then the note is flat, and if LED 4 or 5 (TAP TEMPO)
are “on” then the note is sharp. And obviously, when
LED 2 or LED 4 are “on” it means you are closer to
being in tune with the note in the BANK DISPLAY
than when LED 1 or LED 5 are “on.”
When in TUNER MODE the VC-4 is CHROMATIC,
just like the built-in tuner in your Valvetronix amp.
And just like your amp, it displays the note names
in the BANK DISPLAY as follows:
Note
Name
CF#
C# G
DG#
D# A
EA#
FB
As already mentioned, when your VC-4 is in
TUNER MODE its BANK DISPLAY will show “ ”
or, if in SILENT TUNER MODE, “ ”…unless, of
course, you are playing a note in which case the
BANK DISPLAY will show the nearest note name to
the one you’re sounding. Here’s how you get to
TUNER MODE.

SILENT TUNING MODE
Wanna tune your guitar in silence using your VC4? If you’re playing a gig of course you do! Here’s
how you do it…
i) From PROGRAM SELECT MODE: All you
have to do is hold down the SWITCH of the
selected channel (1-4) for 1.5 seconds. As
soon as the BANK DISPLAY shows “ ”
you’re ready to tune in silence using your VC-
4.
ii) From INDIVIDUAL MODE: Here you have to
switch on the tuner via the Top Panel of your
amp by simply pressing the TUNER/CANCEL
Button for a second or more. As soon as the
BANK DISPLAY shows “ ” you’re ready to
tune in silence.
iii) From MANUAL MODE: Simply hold down the
FX ON & OFF/ CHANNEL SWITCH down for
1.5 seconds. As soon as the BANK DISPLAY
shows “ ” the amp’s output is muted and
you’re ready to tune.
GETTING OUTTA TUNER MODE
Just step on the TAP TEMPO SWITCH and you’re
outta there and back to whatever mode you were in
before you entered TUNER MODE or SILENT
TUNING MODE.
USING THE VC-4 WHEN THE AMP’S IN
M
ANUAL MODE
(just in case you’ve forgotten you can)
As you learned from “The Guitarist’s Guide” that
accompanied your Valvetronix amp, MANUAL
MODE (a.k.a. “what you see is what you get”
mode!) is a pretty cool feature. And, as you’ve
also been reading, whenever the amp is in
switched to MANUAL MODE the VC-4 goes there
as well and “ ” appears in its BANK DISPLAY.
Furthermore, as you’ve also just learned, even
though you can’t get out of MANUAL MODE
using the VC-4 (you have to do that at the amp),
you can enter TUNER MODE and SILENT TUNING MODE by stepping on it. Even cooler is
this…
When your Valvetronix combo is in MANUAL
MODE, your VC-4 works in exactly the same way
it does when it is in INDIVIDUAL MODE!! This
means you can use SWITCH 1 – 4 to switch the
PEDAL, MODULATION, DELAY and REVERB
Sections on/off, use the TAP TEMPO SWITCH to
change delay time and use the BUILT-IN PEDAL
as either a VOLUME or EXPRESSION controller.
And, you can tune your axe in silence too? Pinch
me, it must be Christmas!

Troubleshooting
1. The VC-4 is not powering up when connected to the amp
➢ Is the power on the Valvetronix amp switched
on?
➢ Is the VC-4 properly connected to the Val-
vetronix amp?
➢ Is the correct cable being used?
Please check that all connections are properly
made and that the contacts on the VOX BUS jack
on the rear of the VC-4 and your amp are kept
clean.
2. Effects cannot be switched on/off with the
VC-4
➢ Is the VC-4 in Individual mode?
➢ Are the MOD, DELAY or REVERB sections on
the Valvetronix amp off?
➢ Are the MOD, DELAY or REVERB sections on
the Valvetronix amp bypassed?
➢ Is the correct cable being used?
5. The external volume pedal does not work
➢ Is the connection properly made?
➢ Is the correct cable being used?
➢ Is the cable broken?
➢ Is the external volume pedal compatible with the
VC-4?
Please check the connection and cable. If the external volume pedal allows for a minimum setting,
please set the value as low as possible.
6. The calibration needs to be adjusted on the
built-in pedal and/or an external volume
pedal
In case you aren’t getting the maximum or minimum effect when the pedal or an external volume
pedal is used, please re-calibrate the VC-4 via the
following steps.
TIP! When you calibrate the pedal, use your
hand because using your foot may not enable
an accurate adjustment.
a) Re-Calibrating the VC-4 using the built-in
pedal.
Please check the effect settings on the Valvetronix
amp and make sure the VC-4 is switched to Individual Mode.
3. Effect(s) cannot be heard even if they are
switched on by the VC-4
➢ Are the effects on the Valvetronix amp
bypassed?
Please check the settings on the Valvetronix amp. If
bypass is “on”, none of MOD, DELAY, REVERB
effects will be heard.
4. The pedal on the VC-4 does not control the
effect being selected
➢ Is the pedal set properly?
➢ Is an external volume pedal being used?
In order to get the Expression pedal to function as
an expression controller, keep the TAP TEMPO
button pressed for more than 1 second until the
Expression pedal LED lights up on the VC-4.
Also, check that the EX CTL switch, the setting of
the MOD section and/or the setting of the PEDAL
section on the Valvetronix amp are set properly.
TIP! When hooking up an external volume
pedal to the VC-4 via the volume jack on the
VC-4, the built in pedal automatically reverts
to Expression only and volume is controlled
by the external pedal only.
