Since 1976, the Martin HD-28 has been the D-28's slightly more ornate sibling, with herringbone purfling and scalloped bracing paired with its Indian Rosewood back and sides. The D-28 template just might be what most people think of when imagine an acoustic guitar, thanks in part to its use by thousands of players on stage and in the studio. Despite its simple and clean look, the Martin HD-28 is a revered and precise instrument, guaranteed to make anyone pay closer attention to the sounds you create.
