Martin OM-21 Ambertone Acoustic Guitar

The Martin OM-21 Ambertone delivers classic Orchestra Model balance, vintage-inspired elegance, and premium tonewoods built for serious players. Designed for fingerstyle precision and articulate strumming, the OM-21 combines a solid Sitka spruce top with solid East Indian rosewood back and sides for exceptional clarity, warmth, and dynamic response.

The striking Ambertone finish gives this model a timeless vintage aesthetic while enhancing the natural beauty of the wood grain. Its comfortable OM body shape offers excellent projection with balanced mids and sparkling highs, making it ideal for studio recording, live performance, and everyday playing.

Built with Martin’s legendary craftsmanship, the OM-21 features scalloped X-bracing, an ebony fingerboard and bridge, and a smooth satin neck profile for effortless playability. Whether you’re a fingerstyle guitarist, singer-songwriter, or collector, the Martin OM-21 Ambertone offers heirloom-quality tone and feel.

The OM-21 is prized for its articulate voice, comfortable body size, and outstanding tonal balance. Players love the responsiveness for fingerpicking while still having enough headroom for aggressive strumming. The Ambertone finish adds boutique visual appeal to one of Martin’s most respected Orchestra Model guitars.
