Martin Custom Shop OM-28 Auditorium Blacktop Acoustic Guitar, Spruce/East Indian Rosewood

Martin Custom Shop OM-28 Auditorium Blacktop Acoustic Guitar, Spruce/East Indian Rosewood

The Martin OM-28 is one of the most iconic models in Martin’s lineup, trusted by generations of players for its balanced tone, timeless style, and unmatched versatility. Its Auditorium body size delivers resonance across all six strings, with deep bass, rich overtones, and clear trebles that suit any playing style. Built with a solid spruce top and solid East Indian rosewood back and sides, the OM-28 features a longer 25.4" scale length, offering increased string tension, creating slightly brighter tones and enhanced projection and sustain. The satin neck with a Golden Era (GE) Modified Low Oval profile and high-performance taper ensures smooth playability. Complete with bold herringbone top inlay, antique white binding, and an ebony bridge with bone pins, the OM-28 is a timeless classic for today’s player. Available in a variety of striking gloss options, it’s a guitar you can trust to unleash the artist within. 

Martin’s refreshed Standard Series for 2025 enhances tone, comfort, and style. Sitka spruce GE top bracing, as featured on the Modern Deluxe Series, delivers vintage-inspired tone and sustain, while updates like a reimagined neck profile, thinner fingerboard, and refined bridge and heel improve playability and aesthetics. Each guitar includes a hardshell case.
