Earthquaker Devices AB Box Effects Pedal

The EarthQuaker Devices® A/B Box is a compact, no-fuss solution for switching between two signals or destinations with ease. Its fully passive design means there’s no circuitry in the signal path, giving you clean, uncolored tone whether you’re switching between two amps, two guitars, two pedal chains, or even sending one signal to a tuner or mute. Use it in either direction—input to A/B or A/B to input—for total flexibility on your pedalboard. Clean, simple, and ready for anything. Passive A/B switcher design with no circuitry in the signal path for transparent tone switching between two sources or destinations. Can be used in either direction—input to A/B or A/B to input—for flexible routing. Perfect for switching between two amps, guitars, effects chains, or for creating dry/wet signal paths. Functions as a tuner out or mute switch when needed. Compact and pedalboard-friendly design. True mechanical switching for reliable, noise-free operation. Durable metal housing built for road-ready performance. Current Draw: 10 mA Please note: This device takes a standard 9 volt DC power supply with a 2.1mm negative center barrel. We always recommend pedal-specific, transformer-isolated wall-wart power supplies or multiple isolated-output supplies. Pedals will make extra noise if there is ripple or unclean power. Switching-type power supplies, daisy chains and non-pedal specific power supplies do not filter dirty power as well and let through unwanted noise. DO NOT RUN AT HIGHER VOLTAGES.
