A/B Box

A/B Box

The EarthQuaker Devices® A/B Box is a simple, compact tool that lets you choose between two of almost anything. Due to its completely passive design, there is no circuitry between the input and outputs, meaning it can be used in both directions. Use it to switch between two amps! Switch between two channels on a multi-channel amp! Use it as a tuner out/mute switch! Switch between two instruments! Run a dry path and a wet path! The time to passively choose is now!

  • Dimensions

    3.6875 x 1.8125 x 1.8125 in. (94 x 46 x 46 mm)

    Power

    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!
