This product is used to both clean and lubricate the strings. It also takes care of the fretboard's wood. Use it first before playing to ensure noiseless slides, and then at the end of your show/rehearsal to keep the strings free from any moisture-related degradation which could occure.

I've used exclusively this brand on my pedalboard for a few months now. The sound is clear, all frequencies seem to be correctly rendered, the patches are adjustable and resizable at need with no necesity to ever solder anything -- what more could we ask!? Signal carried through George L's cables sounds WAY better than Yellow Cables and Fastline, a bit ahead compared with Planet Waves, and no obvious difference can be heard when compared with Monster Cables. For a studio/home studio installation it seems like the perfect cable, still unsure whether it would pass the test of playing on stage with it though (shielding seems a bit unsufficient for this -- but this is the price to pay for such a clear signal sound for recording)...
