Ernie Ball instrument cable is specially designed to meet the critical demands of both performers and studio musicians. Ernie Ball Cables maximize your tonal capabilities by capturing your instrument's complete frequency response, natural timbre, and sharp resonance. Low capacitance instrument cable features a 20-gauge, oxygen-free copper core; foamed polyethylene core insulation; and a conductive plastic triboelectric shield to eliminate handling noise. A braided, oxygen-free copper shield yields an additional 95% coverage of RF and EM interference; and a thick, durable and flexible outer jacket.
