It features a solid Sitka spruce top paired with solid genuine mahogany back and sides in a natural gloss finish. Built with a 12-fret D-body size and dovetail neck joint, it incorporates non-scalloped Sitka spruce top bracing, a Style 28 rosette, East Indian rosewood fingerboard and belly bridge, a 24.84-inch scale length, and a 1 7/8-inch white Corian nut. The slotted headstock is fitted with Golden Age side-mount tuning machines with cream plastic buttons.
