Martin Custom Shop 00 Size 28 Style With Wild Grain Rosewood, Bearclaw SpruceAnother masterpiece from the Martin Custom Shop for our Russo Music Select program. We travel to the Martin Factory as often as we can to hand select premium woods for our custom builds. This 00 12 fretter is based on 28 style appointments. The top is a beautiul, snow white High Altitude Swiss Sitka Spruce. This premium top wood not only adds to the sonic character, but it provides a stark contrast to the Wild Grain East Rosewood back and side set.
