This is a rugged A/B-Y switcher pedal, that allows you to switch a common source signal (guitar, bass, keyboard) between two amplifiers or amp channels, or switch two source signals (two different instruments) into the same amplifier. The LEDs show you which of the channels are in use, and the parallel common in/out jacks (4 in total) make switching around so much easier.
