The Circuit Breaker instrument cable with Latching Cut-Off Switch has the same solderless plug connection as its predecessor, but 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 straight and right angle plugs in a variety of lengths. D'Addario 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.
