Now that I've moved onto difficult taping stuff I'm finding it hard to silence strings. Yeah, tying a sock around your fretboard is ok but I'd like a proper piece of kit for it. Do you guys know where I can get one from? I've seen that MACE music (Micheal angelo connection)sell them at the preposterous sum of $89 but that's crazy for something that's practically just a capo that doesn't work!
