Planet Waves PW-AGRA-20

PW-AGRA-20 description:

Planet Waves Circuit Breaker cables have a built-in mute switch to save your equipment from loud pops and squeals when you change guitars with a live amp.

When the button is pushed, the Planet Waves Circuit Breaker cable shorts while remaining plugged into your guitar, making on-stage guitar changes a snap. Once the cable is shorted, remove the cable from the guitar being used and plug the cable into the next instrument. Press the button again to re-activate the cable signal.
