Martin has gone to the trouble of putting more than 900 individual pieces of abalone into the bindings and inlays of the top, sides, back, and rosette of the famousD-45 . Large 'C.F. Martin' abalone letters adorn the headstock; abalone hexagon inlays are used as position markers on the bound ebony fingerboard. To add to the beautiful adornment of this guitar they include a solid spruce top, solid East Indian rosewood back and sides and traditional Martin bracing pattern to generate a fantastic tone.
