For sale is a custom guitar with custom shop paper work from Martin. It is 1 of 7 guitars made for special order and is labeled Custom because it has no model number (picture shown of model name inside stamped Custom)
It is basically a 14 Fret Dreadnought that has a double bound white Boltaron body, Sitka Spruce top, Solid Indian Rosewood back and sides with satin finish, select bound hardwood Performing Artist neck with 1 ¾” nut, FSC Richlite Fingerboard and Bridge, 18:1 Ping tuners and Fishman F1 Analog pickup system with a battery box.
The guitar plays great and has low action. The neck is fast and very easy to play. The Fishman F1 Pickup System has a volume, tone, tuner and two voices by pushing the tone button. This is a great on stage guitar.
I can provide the custom shop paper work from Martin as well as an email from Martin that states this is 1 of 7 custom made guitars. I did write some of the specs below but not all because there is 3 pages of specs.
The case is a very classic green lined case and seems very heavy duty.

My price for this guitar is $2000 obo
