The D’Addario Circuit Breaker instrument cable features an actuated “kill switch” that allows for noise-free instrument changes. Press the switch once to mute the signal to the amplifier completely. Press again to reactivate the signal flow. Available in latching or momentary switches in straight or right-angle plugs in a variety of lengths. Circuit Breaker cables utilize ultra-pure, oxygen-free copper conductors for low capacitance and pure tone. Solderless plugs ensure a solid connection and are easy to fix on the gig with a simple cutter and screwdriver. Two layers of shielding provide 100% coverage for superior insulation and noise rejection, making this the ultimate, high-performance cable.
