The Grand J-28E DN is a double-neck, a six-string and a 12-string on one Grand J body, built in Nazareth with a spruce top in Aging Toner over East Indian rosewood back and sides. Martin says it is the first double-neck it has made in more than a hundred years.
The trim is Style 28, from the back strip to the inlays on both ebony boards, with bone at the nut and pins and compensated bone saddles. The bracing is specific to this guitar: a non-scalloped X with scalloped tone bars. The six-string neck is a Modified Low Oval at 1 11/16" across the nut, the 12-string neck is 1 13/16", and both use High-Performance Taper on a 25.4" scale. A Fishman Double Neck System handles the electronics, and it comes in a molded hardshell case.
It suits a player who moves between six and 12 strings within a set and would rather not change guitars to do it. For a single-neck 12-string on a Grand J body, look at the Grand J-16E 12-String; for a 12-string dreadnought in the Standard Series, the HD12-28.
