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.

Camera one…camera two. Saturnworks offers high quality A/B pedals to switch between two amps, two signal paths, two instruments into a pedalboard, or whatever A/B switching application you can dream up.

If you’re looking for an A/B pedal that can work as an A/B or split one input to two outputs (Y), check out our selection of A/B/Y pedals.

Upgrades and Customizations

We can customize your Saturnworks pedal with various graphics, LED colors, and select component upgrades. Check out our graphics and upgrades page for more info.


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 micro version packs a quality A/B circuit in a tiny 2″ x 2″ enclosure–the smallest A/B pedal out there. The micro version features high quality Japanese Lumberg jacks.

The momentary A/B normally outputs the signal to the lower output jack. With the switch held down, the output switches to the upper jack. With the switch released, the signal switches back to the lower output jack.

The LED versions feature a bi-color LED that allows you to easily see which input is active.

The 9v battery version is large enough to fit a 9v battery and also features a metal battery holder.

The toggle version switches with a toggle, rather a footswitch.

Stereo TS TS +  TRS A/B

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.

Please note: Regarding using TRS A/B switches with expression pedal switching, some devices enter ‘expression mode’ when a cable is connected to their expression jacks, regardless of whether or not an expression pedal is connected or active. These devices may therefore perform unwanted functions, even if an expression pedal is not connected. In those cases, connecting an expression pedal to two devices with a TRS A/B switch may not produce satisfactory results. You can test how your device will behave with an expression connected but not turned on by simply plugging a patch cable into its expression jack with nothing on the other end. Whatever the device does in that scenario, will be what it does with the A/B connected but turned off.

A/B + Kill Switch

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.

A/B Input/Output + FX Loop

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 A/B pedals include boutique grade parts and features including:

  • A compact 1.5″ x 3.5″ (2.5″ x 4.5″ for battery and stereo versions) cast-aluminum enclosure saves space on your board.
  • A unique wiring configuration grounds the unused signal. This eliminates noise caused by the unused signal being left open.
  • High quality switches.
  • Heavy duty Neutrik jacks, or Japanese Lumberg jacks with some TRS applications.
  • A passive design that does not need power to function. Only optional LEDs require power.
  • Handcrafted and bench-tested in the USA.
  • A 1-year warranty against manufacturing defects.

Please note: The pedals in the images are stock photos, not the actual pedals you will receive. The pedals you receive may therefore vary in their graphics, knob colors, and/or LED colors, where applicable. We have our graphics options listed here.
