ABY+
Hum Eliminating Switcher
ABY+ is a pedal that takes your guitar signal and switches it between two separate outputs (A or B) or plays it through both outputs (Y) at the same time.
Output B has a switchable Isolation Transformer and Ground Lift to help reduce hum and noise caused by ground loops.
