The GigRig 321 Guitar Switcher

If you use multiple guitars with varying levels, The GigRig Three2One allows you to switch effortlessly between them and use the built in preamps to balance the levels.

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.

You can choose true bypass or preamp for each instrument.  User programmable functions with optional signal mute pre-sets and gain boosts up to X4.

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.

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!


POWER - 9V to 12V DC centre negative (9VDC recommended). Optimised for use with the GigRig Generator power supply.

CURRENT DRAW - 120mA normal mode, 120mA to 200mA in blend mode.

    The pedal operates well. Was surprised that after paying a 190 for it there I needed to buy a power supply.

    Absolute game changer. I use 2 this all the time now. Essential for me. I use an old passive bass and a new 5 string active along with key bass and the individual gain controls are perfect. Thanks

    Love the Three2One!

    To run several instruments through the same rig is a PITA, but this pedal lets me run a Bass, an acoustic & an electric into my VL3-X & attenuate a balanced signal for all!
    Get this box NOW!!!! You won't regret it.

    Great device for anyone looking to take multiple guitars to a gig. Makes switching out a breeze and levels any mix-match of guitars perfectly so you can stay right where they had you in the mix!

    The three 2 one effortlessly allows me to switch from Telecaster (single coil) to 335 (Humbucker) using the same rig, without the annoying volume change thanks to the preamp/buffer!
    If you play more than one style of pickup this should be a no brainer. Order one today!!
