Martin J12-16GTE model jumbo 12 string acoustic, made in USA and dating from 2013.
 
A wonderfully spec'd Martin 12 string, produced for a limited run with a GTE (Gloss Top Electric) configuration - non cutaway. Plays wonderfully, with a huge sound from the jumbo body, complemented by solid woods and unparalleled build quality from the Martin USA team.
