Martin 2002 D-28 Natural Acoustic Guitar With OHSC - UsedThis Martin D 28 features a Sitka spruce top with very wide and straight grain. The rosewood back and sides have light to dark stripes with a little bit of ripple in the grain towards the lower bottom. The mahogany neck profile is a slim taper with not a lot of shoulder but allows the player to wrap their thumb around the neck very easily. Martin's thin line Gold Plus pickup captures the resonance and depth that this D 28 has to offer acoustically.
