Rudy Blazer and Willi Henkes, building in Tuebingen, Germany, are responsible for some of the best guitars on the planet built in the Martin tradition. This OM, called their San Antonio model, is based on a 1930 OM-28, with herringbone purfling, white binding and traditional OM string spacing. This a particularly sweet, rich, explosive sounding box with perfect balance and super low action. The back and sides are Brazilian rosewood, the top is alpine moon spruce from Austria. The neck is non-adjustable with carbon fiber reinforcement and has the traditional dove-tail neck joint. Condition is fabulous.
