The CopperSound Passive ABY pedal is a simple and handy utility device designed to split one input into two separate outputs, or combine two separate inputs into one output. Being a bi-directional passive device, its applications are only limited by your imagination. Use it to run and organize your stereo rig, switch between two instruments on the fly or even as a mute switch for silent instrument changes. To make connections simple, the footswitch washers are color-coordinated to their corresponding output jack. Since this ABY pedal is a passive device, power is only required for the status LEDs.
