The Radial BigShot ABY is a compact ABY switcher that allows you to switch between two amplifiers or combine the signals to play both amps simultaneously.

Crafted for the purist, this true-bypass ABY switcher is entirely passive, meaning there are no tone-altering buffers between the guitar and the amplifier. With the BigShot ABY, your guitar's pure tone is plugged directly into your amp. For added versatility, the BigShot ABY features a separate tuner output. This 'always on' output continuously feeds your tuner, while remaining out of the signal chain.

In case of hum and buzz issues from ground loops, the BigShot ABY offers a solution with its built-in isolation transformer and ground lift switch. When activated, you can adjust the polarity of the second amplifier to ensure both amps are in absolute phase.
