The EarthQuaker Devices a/b box is a compact, passive tool that allows you to switch between two signal paths with ease. Thanks to its completely passive design, there's no circuitry between the input and outputs, making it bidirectional. Use it to switch between two amps, two channels on a multi-channel amp, or even two instruments. This tiny box brings unmatched flexibility to your pedalboard.

With Passive Operation for Seamless Switching

Switch between two paths without any signal loss, or use it as a tuner out/mute switch. Whether you're running a dry path and a wet path or switching between instruments, the a/b box is designed for ultimate functionality in any setup.
