The 00-15M is Martin's all-mahogany Grand Concert: a smaller-body, intimate-volume 14-fret guitar with solid mahogany top, back, and sides, satin finish, no binding, no inlays. The minimalist Martin — all the construction quality, none of the trim. Mahogany neck with the Modified Low Oval profile, East Indian rosewood fingerboard and bridge, 1 11/16" bone nut, 24.9" short scale, non-scalloped X-bracing.
The Grand Concert (00) body is meaningfully smaller than the Auditorium (000) — narrower at the lower bout, more comfortable on the lap, and noticeably quieter and woodier in voice. All-mahogany construction gives it a dry, midrange-forward sound that sits in a mix without taking it over. The short scale and small body make it forgiving for fingerstyle players, smaller-frame players, and anyone who prefers a guitar that pushes back less.
Where the rosewood D-28 opens up wide and shimmers, the 00-15M stays focused and immediate — the songwriter's guitar, the porch guitar, the late-night guitar. Natural mahogany satin. New from Martin. Comes with the softshell case.
