Sommer Cable SPIRIT XXL Instrument Cable

High-End Instrument Cable for Stage and Studio

The SPIRIT XXL Instrument Cable is Sommer Cable's flagship bulk guitar cable, sold by the metre and finished in a black-transparent PVC jacket. It has earned cult status among guitarists and bass players for its punchy, neutral tone and has been a multiple test winner in the German and international trade press. The cable is built around a single 0.75 mm² oxygen-free copper conductor and pairs it with a dual-shield construction for clean, interference-free signal transfer.

What Sets This Cable Apart

Two design choices make the SPIRIT XXL stand out in its class. First, the dual shielding combines a tin-plated copper braid with a conductive carbon screen under the jacket, achieving 100% coverage that rejects hum and RF interference even in electrically noisy stage environments. Second, the lavishly foamed PE insulation is finished with a special lacquer that the manufacturer says guarantees excellent transmission properties for many years, while the fine 42-strand copper design keeps the cable flexible enough to reel without twisting.

Who This Cable Is For

The SPIRIT XXL Instrument Cable is the right choice for guitarists, bassists and keyboard players who want a professional-grade bulk cable for assembling their own instrument leads, pedalboard patch cables or studio wiring. Its 6.80 mm outer diameter fits standard 6.3 mm jack and Neutrik connectors, and the dual shielding makes it well suited to long cable runs on stage where interference is a concern. Buyers should note that the conductive carbon layer under the braid must be removed when soldering to avoid shorts, and the cable is stiffer than entry-level alternatives — a worthwhile trade-off for the durability and signal integrity it delivers.
