The Martin OM-21 is constructed using a Sitka spruce top, Indian rosewood back and sides, and a mahogany neck. It sports some classic features like a scalloped X bracing pattern, 1 3/4" nut width, and nickel open-gear tuners. The modified low oval neck shape makes for a very easy to play guitar, and the darker sunburst is very striking in person. Comes with the original hardshell case.
