Martin Custom Shop Adirondack/Sinker Mahogany Custom "D-18" Dreadnought Acoustic Guitar #6903

The Martin Custom Shop Adirondack/Sinker Mahogany Custom “D” Dreadnought is a purpose-built instrument created for players who want classic Martin power with boutique-level refinement. Inspired by the legendary D-18 style, this dreadnought pairs an Adirondack spruce top with a premium set of sinker mahogany selected specifically by The Acoustic Shoppe, giving it a rare combination of authority, warmth, and visual character. Finished in a thin gloss with a subtle aging toner and detailed with old-style appointments, it delivers the unmistakable look and feel of a vintage Martin built with modern precision.

This Custom Shop D is all about tone that feels immediate and alive under the hands. Adirondack spruce provides exceptional headroom and dynamic range, while the sinker mahogany back and sides add depth, clarity, and a rich midrange that stays focused even when played hard. The forward-driving dreadnought body moves plenty of air, producing strong fundamentals, a tight and powerful low end, and a clear top that cuts through effortlessly. Whether flatpicking bluegrass, driving rhythm, or digging into expressive single-note lines, this guitar responds with authority and balance across the entire register.

Playability and craftsmanship reflect Martin’s highest standards. A modified V neck profile with a dovetail neck joint offers a confident, traditional feel, while the ebony fingerboard, GE modern belly bridge, and bone components provide stability, sustain, and precise response. Vintage-style Grover StaTite tuners, brown faux tortoise binding, and classic Style 18 inlays complete the understated aesthetic. Built without electronics to preserve its pure acoustic voice and housed in a hardshell case, this Martin Custom Shop Adirondack/Sinker Mahogany “D” is a no-compromise dreadnought for players who want timeless tone, premium materials, and a truly special Custom Shop instrument.
