Martin Custom Shop OM-28 Adirondack Spruce & Indian Rosew

The Martin Custom Shop OM-28 Adirondack Spruce & Indian Rosewood is a masterfully crafted instrument that embodies the rich tradition of Martin’s legendary OM-style guitars while incorporating the finest tonewoods and meticulous craftsmanship. Built with a dovetail neck joint and 000-14 fret body size, this guitar offers the perfect balance of responsiveness and projection. The Adirondack spruce top, supported by Golden Era scalloped bracing, delivers unparalleled clarity, dynamic range, and tonal complexity, making it ideal for fingerstyle players and flatpickers alike.

The back and sides are made from East Indian rosewood, adding warmth, depth, and a resonant low end to its sonic character. Its bold herringbone top inlay and multi-stripe purfling accentuate the guitar’s classic aesthetic, while antique white binding provides an elegant contrast. The modified low oval neck with a high-performance taper ensures effortless playability, complemented by the ebony fingerboard adorned with abalone Diamonds and Squares Long Pattern inlays for a timeless, refined look.

This exquisite guitar is finished with an aging toner gloss top, satin-finished dark mahogany neck, and vintage-inspired nickel open-gear tuners with butterbean knobs. The modern belly ebony bridge and compensated bone saddle enhance intonation and sustain, while the faux tortoise pickguard and bridge pin dots pay homage to classic pre-war aesthetics. Housed in a molded hardshell case, this Custom Shop OM-28 is a true heirloom instrument—crafted to inspire and built to last a lifetime.
