The hand made WOBO True Bypass ABY switch, is used for switching between different outputs. The left switch is used to switch between A and B outputs and the right switch turns on both outputs.

The major improvement in a WOBO ABY is the use of a relay instead of a switch. Most switch based bypass devices use components that are simply NOT DESIGNED for switching audio signals. The relays used in the ABY have been specially designed for switching high-quality audio signals so that there is absolutely no impact on your sound.

The unit also has a ground lift selector switch for getting rid of ground loop problems (common with use of two or more amps) by cutting off the ground on the B output.

Notice: Due to the high power consumption by the relays (approx. 2 x 40mA), the ABY switch cannot be battery powered. But this is not a problem since you can power the unit from your pedalboard's power supply or, if you prefer, we can supply an appropriate power unit.
