Martin Standard Series OM-28

About the Martin Standard Series OM-28

The Standard Series OM-28 is Martin's rosewood Orchestra Model: a 14-fret 000-size body on the long 25.4 inch scale, with a solid Sitka spruce top, solid East Indian rosewood back and sides, scalloped X bracing, a dovetail neck joint, a 1 3/4 inch nut, and an ebony fingerboard and bridge with 20 frets. Herringbone top trim, a Style 28 multi-stripe rosette, abalone diamonds-and-squares inlays, nickel open-gear tuners with butterbean knobs and a tortoise pickguard are standard. It is Plek-dressed at the factory, and no pickup is fitted as standard.

Its specs changed twice. Before 2018 it has a Modified Low Oval neck with the Performing Artist taper, grained ivoroid binding and 2 3/16 inch string spacing at the bridge. The 2018 redesign brought the High Performance Taper neck, antique white binding, a modern belly bridge with a drop-in saddle and 2 5/32 inch spacing, and white plastic bridge pins. The 2025 refresh brought Golden Era scalloped bracing, a GE Modified Low Oval neck, a thinner fingerboard with a beveled edge, a sleeker heel, a long diamond neck transition, a nut set on an angle, a reworked belly bridge and bone pins. The top is aging-toner natural; 1935 Sunburst is an option.

Weighed examples mostly come in at about 4 to 4.2 lb (1.8 to 1.9 kg). It comes with a hardshell case; recent ones are molded.
