Carrying a distinct vintage-inspired design and updated like the D-18 a few years ago, the OM-28 offers many of the features found in Martins pre-war era guitars. The OM-28 is constructed with all the features of the OM-28E Retro without the electronics package. Aging toner and a polished gloss finish are applied to the Sitka spruce top which features 1/4 X scalloped bracing. The polished gloss East Indian rosewood body is edged with ivoroid binding. Like the 000-18, the models neck features a modified low oval profile with performing artist taper with a width of 1-3/4 at the nut and 2-3/16 string spacing for easy playability. Nickel open-geared tuners with butterbean knobs are found with a rosewood headplate, which displays a large old style Martin logo.
