Built with a Pure Bare Copper 20 AWG conductor, insulated with Low Density Polyethylene and then encased by a conductive rubber shell, the center conductor is fully insulated. A spiral shield protects the wire from spurious magnetic fields and is encased in an extremely durable, yet flexible jacket.

PBC is a term most manufacturers would prefer you forgot. Why? Because they don’t use it - it’s too expensive. JUMPERZ respects your audio as much as you. Every JUMPERZ BLUELINE cable is spun from PBC, providing 40% greater conductivity than copper-clad aluminum.

Contrary to accepted cable mythology, oxygen-free copper does not improve the sound of the cable – but it DOES provide greater flexibility before breaking than non-OFC. All JUMPERZ PBC is also oxygen-free, so your cables last a lifetime.

G&H BigFoot Copper-Core Plugs rethink the last 100 years of traditional ¼” plug design. In mass-produced traditional plugs, several subcomponents and contact points are joined together through press fitting, riveting, or soldering. Because passive instruments like guitars are already very high-impedance, each small junction point within a plug can create additional impedance and alter the quality of audio signals, especially when inferior metals and materials are used. G&H BigFoot plugs address these problems by eliminating unnecessary connection points by using Copper-Core construction. The Copper-Core design uses a solid copper rod that runs from the very top of the plug tip through the stem and body of the plug. Inside the plug body, the Copper-Core is joined directly to cable contact. Fewer signal interrupts and fewer metal types in the signal make this the ultimate ¼” plug.
