The OM-28 Authentic 1931 shares Martin’s incredibly significant 14-fret neck Orchestra model innovation with its lengthened 25.4” scale and 1 ¾” neck width. Madagascar rosewood back and sides and Adirondack spruce with Martin’s new Vintage Tone System (VTS) are used to replicate the aged appearance and tonality of the 1931 original. All other appointments and processes, including hide glue construction, hand shaping and assembly, and tucked under bridge plate and bracing, are completely faithful.
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.
