The MXR A/B Box is a versatile pedal that lets you route your instrument's signal to two separate output amp paths, making it ideal for various setups and performance scenarios. You can use it to switch between two amplifiers or run them simultaneously with different effect configurations, allowing you to find your desired sound easily.

The pedal features two clearly labeled A and B channels, with a footswitch to toggle between them. This way, you can quickly switch between two amps during your performance or practice session without needing to manually unplug and replug cables.

Additionally, the A/B Box has a Thru jack that allows you to connect to a tuner, amplifier, or any other device that you want to receive a constant signal. This ensures that your tuner remains functional even when you switch between the A and B outputs.

The A/B Box is built with a heavy-duty die-cast housing, which ensures its durability for the rigors of live performances and studio use. It also features high-quality jacks and switches for reliable performance.

To power the MXR A/B Box, you have several options: you can use a 9-volt battery, a Dunlop ECB003 9-volt adapter, or any of the MXR DC Brick™, Iso-Brick™, and Mini Iso-Brick™ power supplies (not included), providing flexibility in powering the pedal according to your setup preferences.
