Martin Custom Shop 41 Style Grand Jumbo 12 string Adirondack/Wild Grain East Indian Rosewood w/case 3090367
About This Guitar
Serial: 3090367
This Martin Custom Shop 41 Style Grand Jumbo 12-String was built around a Tone Shop-selected set of Wild Grain East Indian rosewood, paired with a premium Adirondack spruce top and Martin’s full-size Grand Jumbo body. The result is a substantial custom 12-string with standout woods and elevated pearl appointments.
The Adirondack spruce top is supported by 5/16" Golden Era non-scalloped X-bracing, also made from Adirondack spruce. Select abalone runs around the top perimeter, while a Style 45 abalone rosette, antique white binding, and Aging Toner give the body a refined traditional presentation.
Wild Grain East Indian rosewood is used for the back and sides and continues onto the headplate. The genuine mahogany neck uses Martin’s GE Modified Low Oval profile with Wide High Performance Taper and a 25.4" scale length.
The bound black ebony fingerboard has a 16" radius, 1 13/16" bone nut, and 2 5/16" string spacing, providing the additional room appropriate for a 12-string setup. Reduced Style 45 hexagon inlays in select abalone and a select abalone C.F. Martin block headstock inlay complete the higher-end appointments.
A black ebony 12-string GE Modern Belly bridge, compensated bone saddle, bone bridge pins with paua accents, and Gotoh chrome tuners complete the build. A Martin 5-ply hardshell case and Custom Shop Credentials Book are included.
