for various reasons I'm contemplating making an electric 1-string bass guitar out of a shovel. It needs some amping, but I suppose a washtub sort of thing might apply. I don't know anything about electric parts and works, but my boy mainly needs a bass E and maybe some sliding to do his part--his bass is a little heavy for him to stand up with long, and the kids are playing the song from "holes". Any ideas or advice?
