STC cables are designed with audiophile quality wire, designed to reproduce the natural tones of your instrument with zero interference. The low 28pF/ft capacitance is the sweet spot for uncolored tone and the AWG24 oxygen-free copper conductor provides exceptional signal transfer. Donner cables reject interference and avoid handling noise with 100% shielded coverage and 95% tinned copper braiding. Traditionally, mechanical tolerances of 1/4-inch jacks can vary greatly causing unreliable connections. Our cables have an external rubber heat shrink strain relief, internal rubber booty strain relief, AND internal metal clamp strain relief. This triple strain relief system allows for many years of trouble-free usage.
