D`Addario PW-AG-20 20 ft Circuit Breaker Cable, 1/4" Jack

Planet Waves' Circuit Breaker cables have a built-in mute switch to save your equipment from loud pops and squeels when you change guitars with a live amp. When the button is pushed, the cable shorts while remaining plugged into you 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.
