I've been repairing some of my old cables lately, one of them being a Fulltone with the old ends (not Neutrik). Apparently, these connectors are never meant to be reused; you have to remove some plastic to remove the plug, and it's full of black goo. The cable itself has 2 center core wires and shielding, like the Evidence Lyric. Now, I've always read that for noise reduction, the shield wire should only be connected to ground at one end (amp end). Guess what? The Fulltone's shield is connected at BOTH ENDS! I've had a pair of these cables for several years. They sound pretty good, but have a good bit of handing noise. Could this be the culprit?
