An MXR Utility Pedal Designed for Modern Rigs
In a pedalboard, we often talk about drive, delay, or reverb... but a good A/B switcher can transform your playing style. The MXR A/B Box fits this logic: a simple, reliable, and immediate tool to control your signal chain without complicating your setup. Whether you're running a "one instrument, two amps" configuration or need a permanent dedicated output, it quickly becomes a go-to.
Who is it for, and in what contexts should it be used?
The MXR A/B Box is aimed at guitarists and bassists of all levels who want to gain flexibility. In rehearsal and on stage, it allows switching between two amps (clean on one side, crunch on the other), or playing through two amps simultaneously for a wider sound. In the studio, it helps multiply takes and tonal options, or keep a tuner permanently connected via the Thru output without disturbing the rest of the wiring.
A / B / A+B Switching and Thru Output: Simple, Effective
The principle is straightforward: plug your instrument into the input, then choose to send the signal to output A, output B, or A+B depending on the song's needs. The Thru output serves as a constant signal pass-through: useful for a tuner always powered, a second monitoring path, or any equipment requiring signal continuity. With its switches and connectors designed to withstand heavy use, this pedal is built for quick changes during a set.
The Sound
Here, the sought-after "color" is precisely the absence of coloration: the MXR A/B Box is a signal router aiming for the most transparent reproduction possible. It emphasizes clean switching and intuitive use, preserving the character of your guitar, pickups, and effects. The result: you build a wider sonic image with two amps, or switch between worlds without altering your playing or settings.

Questions frequently asked
Does the MXR M196 A/B Box allow the use of two amplifiers simultaneously?
Outputs A and B can be activated simultaneously in A+B mode to feed two amplifiers with the same instrument.
Is it possible to leave a tuner connected permanently?
The Thru output provides a constant signal pass-through. It allows connecting a tuner without changing the routing selected between outputs A and B.
What power supply is required for this A/B pedal?
Its operation is passive and draws 0 mA: no power supply is required. A 9 V battery or a 9 V DC adapter are mentioned in the specifications, although no power supply is included.
Does the A/B switching affect the guitar's tone?
The analog circuit is designed to preserve the character of the instrument and any effects already in the signal chain. The pedal provides routing between outputs A, B, or A+B rather than tone processing.
What connectors are present on the MXR M196 A/B Box?
The input is a jack type and the Thru output is also a jack. Outputs A and B are used to direct the signal to the selected amplifiers or effects paths.
