Martin Custom Shop OM-28 Adirondack Spruce & Indian Rosewood / New For 2025

If you’re looking for an acoustic guitar that captures the soul of a vintage Martin while embracing the precision of modern craftsmanship, the Martin Custom Shop OM-28 Adirondack Spruce & Indian Rosewood—new for 2025—is your dream come true. Available now at Eddie’s Guitars, this masterfully built instrument is everything you’d expect from the Martin Custom Shop: rich in tone, refined in style, and built to inspire.

This OM-28 takes full advantage of its premium tonewoods, pairing an Adirondack spruce top with East Indian rosewood back and sides for a sound that’s both powerful and nuanced. The Golden Era scalloped 1/4" Adirondack braces give the top incredible dynamic range and responsiveness—making this guitar equally suited for light fingerpicking or robust strumming. The bold herringbone top inlay and multi-stripe rosette offer a subtle vintage nod, while the aging toner on the gloss top adds warmth and depth to the visual presentation.

The 000-14 fret body size, paired with a 25.4" scale, gives the OM-28 a perfect blend of comfort and projection. The modified low oval neck with a high performance taper feels lightning fast and effortless in the hand, and thanks to Martin’s Plek process, the fretwork is flawless right out of the case. The select hardwood neck, ebony fingerboard, and diamonds and squares long pattern inlays complete a traditional aesthetic that never goes out of style.

Other premium touches include a solid headstock with script old-style logo, nickel open gear tuners with butterbean knobs, compensated bone saddle, and a modern belly ebony bridge with 2 5/32" string spacing for optimal comfort and tone. Weighing in at just 3 lbs 15 oz, this OM-28 is featherlight, responsive, and incredibly resonant.

Whether you’re a stage performer, studio player, or home enthusiast, the Martin Custom Shop OM-28 Adirondack & Indian Rosewood is a serious instrument built for a lifetime of music. Stop by Eddie’s Guitars or order online—this is one you’ll want to see, hear, and feel for yourself.
