The BigShot ABY is a compact true-bypass ABY switcher that enables you to switch between two amplifiers or play through both amps at the same time, while eliminating buzz and hum from ground loops.

Combining two amps and a tuner

The BigShot ABY makes it easy to switch between two amps. With the built-in isolation transformer, hum and buzz caused by ground loops can be eliminated. A separate tuner out keeps this tone altering device out of the main signal path.

Using the BigShot ABY to mute your amp

You can use the BigShot ABY as a simple mute footswitch for quiet on-stage tuning. Simply depress the AB selector switch and the signal going to the amp is turned off. This keeps the signal going to the tuner output always on, allowing you to tune without bothering others.
