Good point John, costs. even at the least expensive. Plywood and pallet lumber. This instrument will probably cost at least $50.00, for tuners and string. Although I have a machine shop near me that sells me music wire by pound.Expect good first rate materials to go about $150.00. Thats a guess. Spaw would have the best thoughts on this as I haven't built one in about 15 years.
