The Martin Super D-18 is a bold reimagining of a classic voice—bigger, louder, and unapologetically powerful, yet still rooted in Martin’s most time-honored traditions. Built in the commanding Super D 14-fret body size, this guitar delivers immense headroom and projection, making it an ideal choice for players who dig in hard, flatpick with authority, or need a rhythm instrument that can anchor an entire band. The dovetail neck joint and long 25.4" scale length contribute to its signature snap, clarity, and dynamic range.
At the heart of the Super D-18’s sound is a spruce top finished in a rich gloss with an aging toner, giving it a warm, broken-in look right out of the case. The top is supported by forward-shifted X-bracing with GE-scalloped 5/16" spruce braces, a recipe that unlocks maximum responsiveness, deep low end, and open, airy highs. Visually, the guitar stays true to Style 18 heritage, with multi-stripe top inlay, an Old Style 18 multi-stripe rosette, black binding, and a classic faux tortoise pickguard—elegant, understated, and unmistakably Martin.
The back and sides are crafted from genuine mahogany, finished in a deep dark mahogany gloss that complements the top beautifully. This tonewood pairing is legendary for good reason: the mahogany adds woody warmth, punchy mids, and excellent note separation, perfectly balancing the Super D’s massive low end. Style 18 back purfling and a clean, unadorned aesthetic keep the focus squarely on tone and craftsmanship.
Playability is equally refined. The neck features Martin’s GE Modified Low Oval shape with a High-Performance Taper, offering a comfortable, fast feel despite the guitar’s substantial body size. A 1 3/4" bone nut and 2 1/8" fingerboard width at the 12th fret provide plenty of room for both intricate fingerstyle and aggressive flatpicking. The ebony fingerboard is inlaid with Old Style 18 abalone markers, while the satin-finished neck enhances smooth, effortless movement up all 20 frets. Every Super D-18 is PLEK-processed, ensuring exceptional fret accuracy and consistent playability straight from the factory.
Premium appointments round out the instrument, including an ebony GE modern belly bridge with a bone saddle, ebony bridge pins, and nickel open-gear tuners with butterbean knobs for classic looks and rock-solid tuning stability. The solid headstock features a square taper, an East Indian rosewood headplate, and Martin’s Old Style script logo, reinforcing its vintage-inspired identity. It ships in a molded hardshell case for maximum protection and is available in both right- and left-handed configurations.
With no electronics to get between you and the wood, the Martin Super D-18 is all about pure, uncompromised acoustic power. It’s a modern cannon built with vintage soul—perfect for players who want traditional Martin tone, amplified by sheer physical presence and flawless craftsmanship.
