Easy switching from one input to two outputs or two inputs to one output.

The A/B pedal can switch a single guitar between two amps, two chains of pedals on a pedalboard, or can be used as a mute or tuner out.

SKU: N/A Category:


Most A/B pedals simply leave the unused signal open. Saturnworks A/B pedals ground the unused signal. This requires more expensive switches and a lot more wiring, but the result is an extremely quiet top-quality switch.

The LED versions feature a bright bi-color LED that allows you to easily see which input is active. The 9v version is large enough to fit a 9v battery and also features a metal battery holder.

The stereo A/B pedals feature pairs of TS jacks, for stereo switching applications.

TRS A/B pedals, which use TRS jacks, are useful for stereo applications. They can also be useful for switching applications with TRS expression pedals.

The A/B + latching kill switch combines an A/B circuit with a latching kill switch. This pedal switches signal paths or turns your signal off altogether. This switch may be hooked up in reverse to switch between two different instruments.

The A/B input/output + FX loop switch is a fairly specific but handy application. It switches between two inputs A/B style, sends the signal though a hardwired loop, and then to an A/B output–all on the same switch. This would be useful if you had two instruments, which you wanted to switch between two amps, but still using the same pedalboard. For example, it would be used if you switch between a guitar and a keyboard, and you want the guitar to go to a guitar amp, your keyboard to go to your keyboard amp, but you want both to share the same pedalboard.

Saturnworks pedals may be customized with various graphics, LED colors, and select component upgrades. Check out our graphics and upgrades page for more info.

    I purchased the A/B with LED to switch channels on my Tonemaster Deluxe Reverb. It works perfectly. It’s quiet, no hissing or popping and the size really saves space on the pedal board. For me, the LED takes the guessing out of which channel I’m using. This is a great pedal for a great price. I am so glad that I found Saturnworks Pedals. I saw you on Reverb when looking for a switch for my JHS Double Barrel, then I went to your site and found the A/B box too. Bought them both. Thanks for making awesome pedals.
