Abstract: A method of manufacturing a musical instrument using relatively thin metal sheet materials is disclosed. A metallic back plate is provided that has a peripheral edge. At least one metallic side plate with a peripheral edge is provided. Each side plate may be bent to conform to the shape of at least a portion of the peripheral edge of the back plate. A neck block and a tail piece may each be fixed to the inside surface of the back plate proximate the peripheral edge thereof. The neck block is adapted to be secured to a neck to the instrument, and the tail piece is adapted to secure two of the side plates together inside the instrument. Each side plate is fixed, such as with the adhesive, to the back plate, neck block and the tail piece. A metallic top plate is fixed to each side plate, the neck block and the tail piece. To the extent that the top plate and the bottom plate overhang or extend outwardly from the side plates, the overhanging portions are then removed with a router or the like.
