Standard guitar/speaker cables compromise performance by using lower grade conventional copper conductors. This can result in signal loss and distortion that cause lower definition, poor dynamics and inaccurate sound. VOX Class A cables use high grade oxygen-free copper cable conductors that yield better clarity and a more natural sounding midrange. The stranded construction has been carefully selected and tuned using the optimum strand gauge and strand count to give the maximum performance for the instrument applications specific to each cable. A precision formulated, polypropylene dielectric material results in stronger signals that yield better high frequencies, and more realistic tonality and nuance.
