collapse expand iconDescription

Martin's Authentics Series guitars are constructed the old way - with hide glue, throughout, and historically-accurate detailing confirmed by using a CAT scan machine located at the Smithsonian Institute. Based on a 1933 OM-18 on loan from Fred Oster of Vintage Instruments, this guitar is constructed with a mahogany back and sides and an Adirondack spruce top using an authentic circa 1933 bracing pattern. Featuring period-correct "OM-18" Authentic-style appointments, right down to the Authentic 1933 neck barrel and heel.

Includes a 533V Harptone style case.
