What is the advantage of low-capacitance cable? The propaudio ultra low capacitance cable lets you hear all the frequencies being produced by your guitar. High cable capacitance kills the high frequencies from your pickups, resulting in a muddy sound and the greater the signal loss. With cables that are paired, or coaxial, the two conductors with insulation or conductor and shielding in between form a capacitor, which holds an electrical charge. The electrical resistance of a guitar cable is insignificantly tiny compared with the impedance of the pickups and controls, so that won’t affect your tone a great deal, but cable capacitance is another matter altogether. A capacitor is formed whenever two electrical conductors are in placed in close proximity, and for a given spacing, the larger the surface area of the conductors, the larger the capacitance. The core and screen conductors of typical guitar cable may produce a capacitance of around 30 picofarads per foot (or 100
