Fender ABY Footswitch

Fender ABY Footswitch, bought new in 2023. Pedal has two operating modes (explained on picture #3 on the bottom of the pedal): changes between A and B, or switches A and B simultaneously. Can be used to have 2 guitars playing out of 1 amp at the same time, or 1 guitar playing out of 2 amps at the same time. Can be powered by a 9V power supply or battery, however this pedal works just fine without a power source (however, the lights won't come on). The only thing a power source does to this pedal is make the lights turn on.
