A unique model a little different than Martin's usual, this 000-15SM is a 12-fret all mahogany model with a slot headstock. The result is a easy to play guitar that really does well with finger picking or a blues feel. From Martin Guitar’s Website: "The 000-15SM offers a vintage-inspired take on Martin’s Auditorium body with a 12-fret neck joint and slotted headstock for classic style and feel. It features all-solid mahogany construction, non-scalloped spruce X-bracing, and a satin finish for a natural, smooth feel. The longer 25.4" scale length and 1 3/4" nut width provide plenty of room for expressive playing, while the Modified Low Oval neck profile ensures comfort across positions. The East Indian rosewood fingerboard includes diamond and square abalone inlays, and nickel side-mount tuners complete the traditional aesthetic. A softshell case is included, and optional electronics are available for players who want to plug in."
