Martin OM-28 Authentics are here! Well, technically, it's the OM-28 Authentic 1931 model, which features their new VTS torrefied Adirondack Spruce top and bracing. Martin's new "Vintage Gloss" finish is a highlight too--featuring a significantly less glossy lustre, yet nowhere near a satiny texture. In short--it's a great idea in the name of the vintage-inspired aesthetic of the Authentic series, and Martin has pulled it off extremely well. The difference in tone is quite substantial as well--these guitars have that dry, woody sound you'd expect to hear in a vintage guitar -- and they're very light and responsive. This is something Martin fans have been clamoring for, and it's a real home run from where we sit. Priced with 533V Harptone case.

Pictured guitar is in stock. Media sample reflects a previously sold guitar with identical specs.
