Product Description The Planet Waves Circuit Breaker plug has fail-safe operation to save your equipment from loud pops and squeals when you change guitars with a live amp. When the button is held down, the cable shorts while remaining plugged into your guitar, making on-stage guitar changes a snap, and eliminating any chance of sound bursts. Once the cable is shorted, remove the cable from the guitar being used, plug the cable into the next instrument, and release the circuit breaker switch to reactivate the cable. From the Manufacturer Planet Waves Circuit Breaker cables feature an integrated mute switch that prevents loud pops or squeals when unplugging your instrument. Simply press and hold the button to activate the mute function, and unplug. When you're plugged in and ready to go, release the switch to reactivate sound.
