This is a limited run 1988 NAMM show guitar. These are super rare in any condition, but are particularly rare in this fine a condition. Unlike it’s 16 series sibling of the time it features a hand fitted dovetail neck joint. It was made using Sitka Spruce top and Mahogany back and sides. It is said Martin discontinued this model because it was too close in specs to the venerable D-18 at a much lower price point. It features an East Indian Rosewood fingerboard and bridge. It has special Grover tuning machines made specifically for this model (see pics). It also features a Martin Thinline 332 passive pickup that sounds great. It is nice and clean was just set up with Martin Lifespan 2.0 light gauge strings. It comes in a hardshell case (I think it is original to the guitar) and the lock on it actually works and it comes with the key.
