Martin's Custom Shop takes the "understated looks" and "timeless tone" of the D-18 and give it a serious tonal upgrade with torrefied Adirondack Spruce. Combining that Mahogany with forward-shifted scalloped bracing and dynamic, stiff Adirondack Spruce for the soundboard delivers up a D-18 with massive rumbling, articulate dreadnought power. The condition of this pre-owned guitar is excellent, with minor signs of handling. Includes its original Hard Case.
