The Martin OM-45 sits at the very top of the Standard Series, bringing together the balanced response of an Orchestra Model with the kind of craftsmanship and appointments that make a guitar feel truly special. Its solid Sitka spruce top and solid East Indian rosewood back and sides produce a rich, resonant voice with impressive sustain, blending sparkling highs, focused mids, and deep, musical lows. The GE-inspired spruce bracing adds a breathier, more vintage character to the response, giving the OM-45 a wonderfully dynamic quality that reacts to every change in your touch.

The genuine mahogany neck features Martin’s GE Modified Low Oval profile, offering a comfortable shape that feels natural from the first chord. A longer scale length adds clarity and projection, while the thinner ebony fingerboard with beveled edges and refined string spacing makes intricate playing feel effortless. The ebony GE modern belly bridge and bone bridge pins further enhance the guitar’s resonance, creating an instrument that feels just as refined under the fingers as it sounds in the room.

Then there’s the visual experience, with pearl inlay, gold open-gear tuners, a vintage-inspired long diamond neck transition, and a full-gloss finish giving the OM-45 an unmistakably elegant presence. It has the visual sophistication of a true heirloom while retaining the balanced, responsive personality that makes an OM such a versatile format for fingerstyle, flatpicking, and everything between. The Martin OM-45 is a stunning expression of Martin craftsmanship and vintage-inspired acoustic tone. Available now at Haggerty’s Music.
