FYI- most music stores, and every guitar center I have ever been in, stock gaffer tape. It's a little more expensive {19.95 at B&H vs 29.99 at Guitar Center for a 50yd roll} but it has saved my butt a few times when I've needed it in a hurry. I volunteered as tech crew in a community theater, and there was one time where I hadn't reordered in time and dress rehearsal was that evening. Makes sense that musicians would need it as well. I'll definitely second that it is really useful stuff, I almost always prefer it over duct tape.
