Martin Standard Series OM-42 Auditorium Acoustic Guitar, Rosewood Back & Sides, Spruce Aging Toner

Manufacturer's Description

The Martin OM-42 is a trusted blend of tone and craftsmanship, designed for players who value exceptional sound and stunning visual details. Its Auditorium body size delivers balanced tone across all six strings, with deep bass, rich overtones, and clear trebles that suit any playing style. Handcrafted with a solid spruce top and solid East Indian rosewood back and sides, the OM-42 offers a resonant voice with enhanced projection and sustain, thanks to its longer 25.4" scale length. The gloss genuine mahogany neck, featuring a Golden Era (GE) Modified Low Oval profile and high-performance taper, ensures effortless playability and precision. Adorned with exquisite abalone details, the OM-42 features snowflake inlays on the bridge and bound ebony fingerboard, a shimmering rosette, and pearl trim on the top that wraps elegantly around the fingerboard. Complete with antique white binding, an ebony bridge with bone pins, and gold open gear tuners, the OM-42 is 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.
