This OM-18 Authentic "1933" is the first that I've gotten to play, and it has really blown me away since coming in to the shop! This Authentic OM-18 features Martin's "Vintage Tone System", or "VTS", which includes the use of torrefied woods to try and recreate the tonal and visual properties of old spruce. Other features include beautiful mahogany back, sides, & neck, ebony bridge, fingerboard, & nut, hide glue construction, and VTS "shadetop" finish. This guitar includes the original Martin-branded Harptone case and all hangtags, paperwork, etc. Demo video coming soon.
