The Circuit Breaker cable's plug is able to cancel all amplifier noise by shorting the signal to ground with the push of a button. Once the button is pushed, the cable can be transferred to another guitar with no hum, noise, or pops; push the button a second time and the cable is active again. The Circuit Breaker is fail-safe, unlike other shorting plugs that use springs to short the plug after it's been removed from the guitar -- which can lose tension and malfunction. |
