The D'Addario Circuit Breaker instrument cable is equipped with an actuated "kill switch" for noise-free instrument changes. A single press mutes the signal to the amplifier, and pressing it again reactivates the signal. It comes with either latching or momentary switches, and is available with straight or right-angle plugs in various lengths.

The cables feature ultra-pure, oxygen-free copper conductors for reduced capacitance and a purer tone. The solderless plugs ensure a reliable connection and can be easily repaired during a performance with just a cutter and screwdriver. Dual layers of shielding provide complete insulation and noise rejection, establishing this as the ultimate high-performance cable.
