The D-18 Authentic 1937 is Martin's recreation of a Golden Era D-18, put together with hide glue. The top and braces are Adirondack spruce with VTS, scalloped in the Forward Shifted X Brace pattern, over genuine mahogany back and sides, and the neck is genuine mahogany too. The whole guitar wears Vintage Gloss, with a clear top.
The neck follows the Authentic 1937 shape with the Standard Taper and a 1 3/4" nut, widening to 2 1/4" at the 12th fret. At the bridge, an Authentic Belly with a glue-in long saddle sets the strings 2 1/4" apart, which gives the picking hand more room than the 2 5/32" spacing on the Standard Series D-18. Brown tortoise pattern binding, a Madagascar rosewood back strip and headplate, Old Style 18 abalone inlays and Waverly nickel open-back tuners round out the period details.
Martin describes a dry, punchy pre-war sound. For the same guitar with an aged finish, look at the D-18 Authentic 1937 VTS Aged; for Guatemalan rosewood, the D-28 Authentic 1937. The Custom Shop D-18 pairs Adirondack and genuine mahogany with a modern neck.
