This Martin CS-OM-13 is part of a limited run of 80 guitars that were built in 2013. The top is Swiss high-altitude spruce, which was harvested in the winter months to produce a lighter-weight wood with better stiffness, and a tight and even grain. The back and sides are Madagascar rosewood, and the fingerboard is inlaid with pearl scalloped diamonds and red spiny reconstituted stone with a mother of pearl border. This CS-OM-13 was constructed using hide glue. It’s in excellent structural and cosmetic condition with just a very few minor signs of having been played. The frets show a little wear but they are in otherwise good condition and have lots of life left in them. Includes the original custom shop case.
