This model is part of Martin's "reimagined" Standard Series, which means there are some different specs than earlier Martins with the same model code. For the most part, what Martin has done is migrate many of the features previously reserved for their Vintage Series to these Standard Series guitars.

New specs for these Standard Series models include: Scalloped X top bracing. Ebony fingerboard and bridge. Neck is 1 3/4" wide at the nut. Faux tortoiseshell pickguard. Antique white binding. Vintage style open-back tuners (Schaller Grand Tune on this model). Original style gold Martin decal on headstock. Slightly toned finish (natural spruce top not as "white") .
