This is a custom made guitar made by Bill Sterling of Greenman guitars. It is a new instrument that has been to some guitar shows but remains close to its mint condition. This guitar has lovely even tone and stylistically is reminiscent of a Martin D-18. It features all solid woods including a solid Sitka Spruce top and Mahogany back and sides.  I also features gold plated tuners and a nice tortoise pick guard. Grab this nicely made hand built at a nice price as they don't come around often. Comes with Martin style hard shell. Bill's bio below:
