A satin, all solid wood mahogany model, the 000-15M is a great sized guitar and has found popularity with blues musicians and a song writing companion.
From Martin Guitar’s Website: "The 000-15M pairs Martin’s Auditorium body with all-solid mahogany construction for a warm, focused sound and a smooth, balanced feel. It features a mahogany top, back, and sides, non-scalloped spruce X-bracing, and a traditional satin finish that gives it a natural, broken-in look and feel. The longer 25.4" scale length adds punch and clarity, while the 1 11/16" nut width and Modified Low Oval neck profile offer easy playability across styles. The East Indian rosewood fingerboard includes diamond and square abalone inlays, and nickel open-gear tuners complete the classic look. A softshell case is included."
