About This Guitar

Serial: 3070398

This Martin Custom Shop 0-18 brings premium Custom Shop materials and vintage-inspired construction to Martin’s compact 0 body. Built with an Adirondack spruce top, genuine mahogany back and sides, and hand-shaped Golden Era scalloped bracing, it delivers the direct, focused voice that makes small-body Martins so rewarding to play.

The Adirondack spruce top gives this guitar clear trebles, strong headroom, and a more dynamic response than you might expect from its compact 0-14 Fret body. Genuine mahogany back and sides keep the voice warm and dry, with punchy mids and a focused low end that works beautifully for fingerstyle, songwriting, recording, and light flatpicking.

The hand-shaped Adirondack Golden Era scalloped X-bracing helps the guitar stay open and musical, while the short 24.9" scale length gives it a relaxed feel under the hands. The genuine mahogany neck features a GE Modified Low Oval profile, paired with a 1 3/4" nut width and ebony fingerboard.

Finished in Vintage Gloss with Aging Toner, the Custom Shop 0-18 keeps its look classic and understated. Old Style 18 fingerboard inlays, nickel open-gear tuners, an ebony bridge, bone saddle, and faux tortoise pickguard complete the build.
