Greven Prairie State - Master Grade Adirondack/Cuban Mahogany (2010)This wonderful guitar, built by master luthier John Greven in 2010, is warm and super responsive, with clear and very deep bass. A full 17 inches across the lower bout, is has a huge sound, but is surprisingly comfortable to play with its curvy shape and wonderful set up. It is in excellent shape, with one small ding on the bass side of the neck by the 7th fret (pictured), and a few very small scratches in the finish which are difficult to see and do
