This is a one-of-a-kind Martin we commissioned from the Custom shop.  We personally selected the woods at the Martin factory in Nazareth, PA and did all the design work and specs.  It is a 14-fret 3 piece back Dreadnaught made with Cocobolo back and sides with a Koa wedge and head place.  This is number two of a five guitar run we did (all unique builds). It sounds as beautiful as it looks.  Wood selection is the key part of a guitar and if there was ever an example of this, this guitar is it!
