Signature Models

The OM-45 is the crown jewel of Martin’s Standard Series, pairing elegant pearl appointments with premium tonewoods, Golden Era bracing, and impeccable playability for players who want the very best. The Martin OM-45 is a pinnacle of craftsmanship in the refreshed Standard Series, combining classic appointments with modern enhancements for a truly exceptional instrument. This all-new full-gloss OM acoustic is crafted with solid East Indian rosewood back and sides and a solid spruce top, delivering a rich, resonant tone with remarkable sustain. The Sitka spruce Golden Era (GE) top bracing, as featured on the Modern Deluxe Series, offers a more vintage, breathy tone. The ebony GE modern belly bridge, with slightly smoother corners and bone bridge pins, enhances resonance and comfort, while the genuine mahogany neck with its GE modified low oval profile and longer scale length ensures a smooth, effortless feel. Playability is key with the OM-45, featuring a thinner ebony fingerboard with beveled edges and refined string spacing for maximum comfort. The pearl inlay, gold open gear tuners, and vintage-inspired long diamond neck transition offer an elegant touch, making this guitar as stunning to look at as it is to play. Wherever you’re performing and however you play, the Martin OM-45 delivers a balanced, dynamic sound with a classic, vintage vibe that’s 
anything but standard.
