OK, so the tone pot in my T-bird was crackling an popping thru my amp (especially when it is NOT turned all the way up). I was told that contact cleaner would fix it. Well, it did, but I find that after a couple or three days (maybe 1 or 2 in between of non-use) it starts to act up again. Anyone know any other little tricks, or is it time for a new pot? Has By T-bird developed a nasty addiction ??
