THE WYE ABY BOX
Versatile 2-way signal routing tool
Instantly switch between two inputs or two outputs, or use two inputs or two outputs simultaneously.
For example: switching between two different amps or amp channels; or quickly switch between guitars in a single amp.
In mode A or B, the pedal is used to select input/output A or input/output B. In mode Y (A+B), input/output A and input/output B are used simultaneously, and the pedal is inactive.
