Martin OM-18 Authentic 1933 Acoustic Guitar Authentic & Vintage Series

Here to remind you why you fell in love with us in the first place, the new Authentics 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 genuine 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. Martin’s new Vintage Tone System (VTS) is employed for the top and braces.

The new Martin Vintage Tone System (VTS) uses a unique recipe that is based on the historic torrefaction system. The VTS acts much like a time machine in which Martin can target certain time periods and age the top/braces to that era. This focused method allows Martin’s craftsmen and women to recreate not only the pleasing visual aesthetics of a vintage guitar, but also reproduce the special tones previously reserved for vintage instruments.
