JGK GOLDLINE Keyboard Cable is the Premium stereo unbalanced keyboard cable solution from JUMPERZ. The heart of JUMPERZ JGK cable is Sommer SC-Onyx 2025 MKII from Germany. This remarkable twin cable is designed to transmit audio signals with accuracy and low noise. Each side features a flexible litz design with its own insulated conductor and helical copper mesh shield for noise rejection.

Each cable end is terminated with gold-plated G&H BigFoot Copper-Core ¼” plugs. 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.
