Planet Waves' Circuit Breaker cable is a low capacitance coax cable featuring a built-in mute switch. The switch allows you to silence the cable during guitar changes onstage with your amp live. You push the button once to mute the cable, thus preventing loud pops or crunches that can potentially damage speakers and startle the crowd. Once the cable is muted, switch guitars, then push the button again to activate the cable. It’s very simple and an elegant solution to a real onstage problem every guitarist who changes instruments has experienced.

Like the Custom and Custom Pro cables, the Circuit Breaker’s plugs are gold-plated but use a set screw-style of strain relief, and the termination of these cables is a solderless die-cast design. Of all Planet Wave instrument cables, the Circuit Breaker has the lowest capacitance rating and best signal transparency.

Planet Waves must have determined this using sensitive instruments for measuring capacitance and such. Personally I couldn’t hear any detectable difference among any of these cables—even the Classic seemed perfectly transparent. No noise. No interference. Just great sound. Maybe some of you out there have bigger ears than me, but I would be happy to use any Planet Waves instrument cable. All are great cables and their lifetime guarantee of reliability is unbeatable.
