A Train-themed Tribute to Martin's Mighty Orchestra Model

Complete with a commemorative RGM watch and some of the finest inlay work to ever roll through Sweetwater’s doors, the Martin OM 20th-century Limited acoustic guitar is a stunning showcase of Martin’s highest degree of 6-string artistry and craftsmanship. This long-scale Orchestra Model’s VTS-aged Sitka spruce top and Guatemalan rosewood back and sides come together to deliver a rich and robust response dripping with shimmering trebles, booming bass, and a nearly unmatched dynamic range. A chunky genuine mahogany neck in a stout Vintage Deluxe profile supports this guitar’s glassy ebony fingerboard, glimmering with attention-demanding art deco inlays and finished off with a captivating and complex train-themed headstock design. Furthermore, the OM 20th-century Limited continues Martin’s partnership with premier American watchmaker RGM with an heirloom-grade railroad-inspired mechanical watch. Limited to but a handful of models worldwide, this once-in-a-lifetime OM won’t last long — Sweetwater will only receive a single Martin OM 20th-century Limited guitar and when it’s gone, it's gone for good!

Rich, resonant tonewoods

Underneath the OM 20th-century Limited’s elegant exterior lies a powerhouse pairing of world-class tonewoods, comprising a VTS-aged Sitka spruce and gorgeous Guatemalan rosewood back and sides. First up, this showpiece instrument sports premier Guatemalan rosewood back and sides — a tonewood that epitomizes traditional rosewood’s shimmering highs, subtle mids, and robust bottom end. Guatemalen rosewood is treasured by fine tonewood aficionados as one of the most striking timbers found on acoustic instruments, brandishing dazzling grain lines and complex 3-dimensional figuring.

Atop the OM 20th-century Limited’s Guatemalan rosewood body sits a VTS-aged Sitka spruce top. Prized by fingerpickers and flatpickers alike for its sweet response and remarkable dynamic range, Sitka spruce is a superb do-it-all top wood with resonance and articulation to spare. Finished off in Martin’s long-scale OM (Orchestra Model) body shape — often argued by Sweetwater’s Martin devout as the most versatile model the brand has ever produced — the OM 20th-century’s superlative sonics more than match its masterful construction and gallery-grade aesthetics.

Emblazoned with artistic train-themed inlay work

From the mesmerizing train-themed headstock to the Art Deco-inspired inlays on the fingerboard, rosette, bridge, and pickguard, the Martin OM 20th-century Limited represents a true masterclass in 6-string elegance. Every inch of this instrument is decked to the nines with handsome appointments, taking the rustic charm of Martin’s old-school Orchestra Model to bold new heights. Last but not least, the OM 20th-century Limited comes paired with an opulent railroad-inspired mechanical watch from RGM — one of the most well-respected modern watchmakers on the planet, granting you lifelong artifact crafted with the same master-grade care and quality as the Martin OM 20th Century Limited.

Woods aged to perfection with Martin’s VTS

Tone connoisseurs are always in search of the perfect guitar tone, and in the acoustic world, one of the most loved tones is that of a vintage Martin. We’re talking guitars that have aged well over 50 years. Martin Guitars recently perfected a unique way of torrefying the top woods and braces of their guitars to achieve the sound of an aged and broken-in Martin. The Vintage Tone System (VTS) lets Martin age the woods to a specific age/time period without the typical change in color of the wood from the torrefaction process. A special vintage gloss finish is then hand-applied to give the guitar the coloring of a vintage instrument. Martin’s guitars with VTS tops not only look like vintage guitars, they also have that sought-after sound.

Martin OM 20th-century Limited Acoustic Guitar Features:

  • Extremely limited-edition model emblazoned with elegant art deco-inspired and train-themed aesthetics — Sweetwater only gets 1!
  • VTS-aged Sitka spruce top captures the dynamics and rich resonance of a perfectly worn-in vintage instrument
  • Gorgeous Guatemalan back and sides supply sparkling highs, cavernous lows, and beam with beautiful grain and figuring
  • Genuine mahogany topped with a sleek slab of ebony
  • Classic Martin OM-style body complete with booming X-bracing
  • Premium Waverly Gold open-back tuners
  • Elegant European flamed maple binding wrapped around the body
  • Old-school pyramid-style bridge with a modern drop-in saddle, complete with Liquid Metal bridge pins
  • A masterclass in tasteful inlay work, from the art deco fingerboard inlays to the resplendent rosette/pickguard work to the headstock’s stunning train-themed artwork
