TheGigRigTM Three2one
Many Thanks for buying TheGigRig Three2One Guitar Selector!
Key Features:
•Road ready tough steel enclosure with unique GigRig designed
marine grade stainless steel Optokick footswitches.
•Custom designed switchable pre-amps with cut & boost control
to accommodate different pickups & active guitars.
•User selectable internal buffer to facilitate long cable runs or
true bypass.
•User programmable functions with optional signal mute pre-
sets and gain boosts up to X4.

In Use:
The GigRig Three2One guitar selector features three inputs. You can
now switch easily between 1-3 guitars or even line level inputs such as
a keyboards or drum machines!
After plugging your instruments in simply use the footswitch to cycle
through them. Need more inputs? You can link 2 units together for up
to 6 guitars.
If you need to balance levels between differing instruments, then
simply select the adjacent preamp button. This engages the pre-amp
gain controls next to the LED displays. You can then easily cut or boost
the individual inputs.
About the GigRig Custom designed pre-amp:
It’s awesome! We’ve doubled the voltage internally from 9v to 18v, so
the Three2One has massive input headroom and can easily cope with a
huge range of differing guitar pickup types (including active pickups),
but remains ultra clean and quiet.
However, without the preamp selected, the guitar is true bypass; your
guitar signal passes straight through. With the preamp selected
(button pressed in) you can use the corresponding gain control to set
your guitar’s level, cut/ boost or simply set it to unity gain that will also
give you a buffer, which helps keep your signal clean and strong over
long cable runs.
About the Optokick Footswitch
The Three2one uses the exclusively TheGigRig designed Optokick
footswitch. It’s milled from incredibly tough marine quality stainless
steel. The Optokick footswitch uses light instead of potentially un-

reliable mechanical switching. We firmly believe it’s the most reliable
footswitch in the world!
In Use:
Using inputs one and two first; the Three2one will ignore the third
input and will only switch between the two guitars in inputs in use.
(Blue and Green). When input three is also used, then Three2one will
then automatically sense a third input being connected and will cycle
through all 3 inputs.
Option: More than three Guitars? Use two Three2one units!
Connect two units together with a ¼” TRS (stereo) cable to connect up
to 6 guitars. Pressing the footswitch on one unit will mute the other
unit. You can use either units’ output to connect to your pedalboard or
amplifier.
Special Functions:
Tip… It’s best to disconnect the output before re-configuring your
Three2one, or just turn down your amplifier if you prefer. To enter the
Special Functions menu simply hold down the footswitch when
applying power to the Three2one. You will then see some of the lights
are on and others are off, this tells you the current configuration. To
change the configuration, press the footswitch once. The Red light will
flash five times. If you press the footswitch again whilst the light is
flashing the Red function will be toggled, you will see that the light will
have changed its state.
The next press will take you to the Green function and the next to the
Blue function. Simply press the foot switch again whilst the light is
flashing to change the Three2One operation. (This change is stored by
your Three2one.)
Tip: Selecting the Blue function immediately takes you to Blend
mode*.

What do the functions do?
Red ‘on’:
This means your Three2one will always step through all three inputs,
even if an instrument is not plugged into input 3, the Red input.
Tip... if you want to have a single input and scroll through the different
pre amp levels, you need this function to be turned on.
Green ‘on’:
This adds a ‘mute’to the guitar selection sequence so now the new
sequence will be Blue, Green,Red, Mute, Blue, Green,Red, Mute;
And so on. This also applies to the two-guitar setup which will then be
Blue, Green,Mute, Blue, Green,Mute; and so on.
*Blue ‘off’:
Blue will always be ‘on’in the standard modes, but turning it off allows
you to blend between the guitars which have the amplifier/ buffer in
the signal path.
This allows two or three guitars to be played at the same time though
the Three2one, it will blend them together with the volume controls as
balance controls.
When in Blend Mode the foot switch will cycle through all the
combinations of the three inputs. This setting will not be memorised
by Three2one so it won’t affect any of your other settings.
Experiment and have fun; even line level devices such as drum
machines or keyboards can be blended with your guitars!
Tip: You can exit back to normal mode, at any time, by simply
removing and reconnecting the DC power.

Re-configuring the output driver:
To re-configure the Three2one’s output driver you must carefully
remove the DC power and then remove the 3 input jack plug nuts and
loosen the out and in jacks. Then unscrew the four screws on the end
of the Three2One. The bottom plate now can be removed, and you’ll
see the DIP switches.
Your Three2one has 4 output driver configurations.
1, True bypass (output direct connection, no amp or
buffer) is selected by an internal mini dip switch; this is
the default mode.
2, Always buffered: this is for systems where long
cables need to be driven with a low impedance to
create a crisp top end to all your sounds. (Never true
bypass)
3, Always X2 - this gives the same benefits as 2 but now
has the added option of increasing the drive range
available*. With the gain control turned all the way up
there will be an increase in signal level of X4 instead of X2.
4, Single Input Cycle: This mode enables you to use a
single input and toggle through the different preamp
levels. You don’t need a preamp engaged but it is
always buffered.
*Note: This would limit the input handling; however, the X4 gain in the
Three2one can still handle inputs of 4V signal peak to peak.
Enjoy!
