The OM-28 is Martin's 000 body on the longer 25.4" scale, with East Indian rosewood back and sides, a spruce top and Golden Era Scalloped X bracing. Bold herringbone runs around the top, with a Style 28 multi-stripe rosette, abalone diamonds and squares on an ebony board, and a bone nut and compensated bone saddle. The neck is the Golden Era (GE) Modified Low Oval with the High-Performance Taper, 1 3/4" at the nut.
It suits a fingerstyle player who wants rosewood and herringbone in a body smaller than a dreadnought. Martin credits the long scale with extra projection and clarity. For the same body and woods on the 24.9" scale, look at the 000-28, and for a rosewood dreadnought with herringbone, the HD-28. The OM-28E is this guitar with a Fishman Aura VT Blend.
All three finishes are gloss and built the same way: the standard top in Aging Toner, the Gloss 1933 Ambertone, and the Gloss 1935 Sunburst. Ours would be the 1933 Ambertone, which takes the top a shade warmer and still leaves the grain and the herringbone in plain view.
