The MXR A/B Box is a simple but incredibly useful utility pedal that allows you to route a single instrument signal to two separate outputs. Whether you're switching between two amplifiers, sending your signal to different effects chains, or maintaining a constant feed to a tuner, the A/B Box gives you reliable, noise-free signal management in a compact, roadworthy design.
Built with MXR's renowned durability, it's an essential tool for players looking to simplify complex setups and unlock greater flexibility from their rig.
The MXR A/B Box may not be flashy, but it can completely transform how you use your rig. Many players buy it to switch between two amplifiers, but its usefulness extends far beyond that. It can be used to separate clean and effected signals, feed a tuner continuously, switch between different pedal chains or create expansive dual-amp setups that would otherwise be difficult to manage on stage.
What we particularly like is its simplicity. There's no menu diving, buffering or complicated setup, just reliable switching that does exactly what it's supposed to do every time you step on it.
For guitarists running multiple amplifiers, worship players using wet/dry rigs, studio musicians or anyone looking to add flexibility to their signal chain, the MXR A/B Box is one of those utility pedals you'll wonder how you managed without.
