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 like to count switch presses rather than look at the light, then this mode is ideal for you.
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.
User selectable output configuration options:
Your Three2one has three 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.
*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!
