Spaw, he's going to have to install some electronics in his guitar before the type of tape you described will work.

Anyway, Joeler, here are two thoughts. Regardless of what kind of tape you use, fold over about 1/4" (6 mm) of the end of each tape strip, sticky side to itself, to form an easy to grap handle for peeling it off in the future. It might also be possible to find some self-adhesive labels to write your lists on, that would hold better than post-it notes but peel off easier than other kinds of tape (be sure to fold one side or corner over as described above). I don't know which kind of labels to recommend, but be careful because I'm sure some of them stick like the dickens. Hope this helps.
