Description
The Martin Custom Shop 000-18 answers strong player demand for a premium 000 body size, delivering a high-end Custom Shop offering built from incredibly sought-after materials. This 000-14 Fret model pairs a solid Adirondack spruce top, finished with an aging toner for a vintage, broken-in look, with genuine mahogany back and sides for warm, focused tone with plenty of headroom. Hand-shaped Golden Era scalloped X-bracing under that Adirondack top adds touch-sensitive dynamics and extra projection without giving up the format's natural balance.
Where the 000 body shines is the balance between projection and control — more low-end presence than a Concert or Grand Concert, but a tighter, more focused voice than a Dreadnought, which makes it a natural fit for flatpicking, fingerstyle, and singer-songwriter work where clarity matters as much as volume. The 24.9-inch scale length keeps string tension comfortably loose, and the GE Modified Low Oval neck with its High-Performance taper stays easy under the hand whether you're working through open chords or reaching for upper-fret leads.
Appointments lean vintage throughout: an ebony fingerboard and bridge, Old Style 18 abalone inlays, faux tortoise binding and pickguard, and an East Indian rosewood headplate with the Authentic Style script logo tie the whole instrument to Martin's pre-war aesthetic. Nickel open-gear tuners with butterbean knobs keep tuning stable without looking out of place, and it ships in a hardshell case, pre-strung with Authentic Acoustic Lifespan 2.0 Phosphor Bronze Light strings. Built left-handed, this 000-18 is a great fit for a left-handed player who wants genuine Custom Shop craftsmanship without stepping up to a full Dreadnought.
