2026 Martin Custom Shop D-18 "2025" Acoustic Natural

Martin’s Custom Shop D-18 2025 provides you with all the tone, vibe, and feel of a golden-age classic, elevating the D-18’s refreshed 2025 formula with a smattering of prewar-inspired specs. Foremost among these is an Adirondack spruce top — the top wood of choice from the D-18’s dawn until the late 1940s, revered to this day for its unsurpassed projection and punch. Coupled with hand-shaped Golden Era scalloped X-bracing and traditional Style 18 mahogany for the back and sides, this Martin Custom Shop D-18 2025 booms with the best of them, resounding with rumbling bass, exceptional warmth, and crisp top-end clarity. A genuine mahogany neck in Martin’s GE Modified Low Oval profile tweaks this otherwise vintage-spec setup with a subtle dose of modern performance. It's all capped off with the understated charm of a vintage D-18, from the ebony fingerboard’s Old Style 18 inlays to the open-back Grover tuning machines. For Martin fanatics who require the best in both prewar tone and modern playability, it simply doesn't get any better than the Custom Shop D-18 2025.
