DiMarzio instrument Cables are unsurpassed for connecting basses amps. Exceptionally crisp, clear, quiet and durable, they outperform cables costing much more. They've been called "the new industry standard," and have successfully passed Guitar Player magazine's "chop" and "jump rope" tests as well as many other torture tests. Custom designed low-capacitance American-made copper cable ensures low stage noise and guarantees consistent sound and improved high frequency response. DiMarzio Instrument Cables are encased in a durable nylon braided jacket which is designed to lie flat, decrease tangling and protect the cable.
