I installed the FURUTECH FP-703 (G) Jack 6.35mm Mono Gold plated Ø8mm (Unit) cable. Although this coaxial cable is for use for other purposes, I used it as a guitar cable. I deal with the production of these belts and I must say that I've never heard such a fantastic sound. Virtually no bass distortion, very singing sound with voice and unlimited details. Well, just nirvana.
