The carcase and frame is all made from a single 40 year old air dried Appalachian black walnut board. The two panels are resawn and book matched from a single off cut of Indiana black walnut saved from the burn pile. The finish is four coals of 1-pound cut amber shellac, well rubbed out with 0000 steel wood after each coat. The whole is finished with a coat of Liberon brown paste wax. The knob is an ebony violin tuning peg. Closure is achieved by a rare earth magnet and a steel screw.
