A smallish gourd from a farm just south of town, a leftover chunk of swamp ash from the basement, pre-enjoyed gut strings, and an old warped drum head that I somehow inherited years ago when a percussionist buddy of mine died. The gourd was so small I decided to make a "pre-Sweeney" four-string twanger. Cash outlay - about $16. (Canadian) for gourd, tacks, and fiddle pegs. It's not really loud, but it ain't bad for something made out of a vegetable. I'll post a tune on it soon.
