This Martin D-16 dreadnought acoustic dates to 2004 and has a number of high-end appointments that are no longer offered on this model.  It has a spruce top and what looks to be sapele back and sides.  The back has a herringbone center strip and the top has multi-ply binding.  The top has a teardrop shaped tortoise pickguard and an abalone (or mother of pearl...I don't really know!) rosette to match the dots on the fingerboard (I think the fingerboard is ebony).  There is a Martin-licensed Fishman Prefix Premium Blend active pickup system installed that we assume was NOT done at the factory since that would make the guitar a D-16E.  Overall, the guitar is in good condition.  There are a few dings/nicks on the guitar as would be expected from 15 years of use but no cracks or repairs that I can see.  There is a spot near the sound hole from a sticker that we removed.  The guitar comes in a hard shell case.
