The MXR M196 A/B Box Signal Switcher is a compact guitar effects pedal designed to route your instrument’s signal between two different paths. It’s a simple, practical tool for guitarists and bassists who want to switch between amplifiers, signal chains, or setups without unplugging cables during a performance.
An A/B switcher lets you direct one input signal to either of two outputs, depending on how you connect it. Typical uses include:
Switch between two amplifiers: Send your guitar to amp A or amp B.
Switch between two signal chains: Choose different effects setups for clean and distorted tones.
Switch between two destinations: Route your instrument to separate rigs for different songs or playing styles.
Reduce cable swapping: Change your signal routing with a footswitch instead of manually unplugging and reconnecting cables.
