The HD-28 is one of the best looking and playing guitars by Martin. It features the classic 28 specs: Spruce top, rosewood sides and back, ebony fingerboard and bridge. What makes it special is the herringbone binding on the top and zipper across the rosewood back. It's got an understated beauty that would make anyone say "there's something special about that guitar but I can't put my finger on it." 25 3/8" scale length and a 1 11/16" nut width. This guitar plays great and has nice comfy low action. Comes with the original martin plastic molded hard shell case.
