The Custom Shop D-18 is a 14-fret dreadnought in genuine mahogany with an Adirondack spruce top in Aging Toner. The braces are Adirondack as well, hand-shaped and GE-scalloped in the Forward-Shifted X-Brace pattern, and the trim leans old: faux tortoise binding and guard, an Old Style 18 multi-stripe rosette, Old Style 18 abalone inlays on ebony and an East Indian rosewood headplate with an Authentic Style script logo.
The neck is a GE Modified Low Oval with the High-Performance Taper and a 1 3/4" nut on a 25.4" scale, with a bone nut and saddle and nickel open-gear tuners. Martin's description is of a strong, resonant dreadnought.
Next to the Standard Series D-18, the changes are the Adirondack top and bracing and the genuine mahogany. For the hide-glue build with VTS-aged woods and a 1937 neck, look at the D-18 Authentic 1937. We'd point a player here who wants an Adirondack top and the High-Performance Taper neck together.
