Product Description
The Martin Super D-18 takes the legendary Dreadnought sound to the next level with our largest body size yet. Building on the silhouette of the iconic Dreadnought, the Super D boasts an internal air volume nearly 20% greater than its predecessor, creating a massive, harmonically rich voice that delivers more sound with less effort. Whether you’re on stage, in the studio, or simply playing for yourself, this instrument offers an extended dynamic range that’s impossible to ignore.
Crafted with a solid spruce top and genuine mahogany back and sides, the Super D-18 produces a tone that’s clear, focused, and powerful. Spruce adds articulation and projection, while mahogany contributes warmth and punch in the mids, making this guitar a responsive choice for flatpickers and strummers alike. The forward-shifted Golden Era scalloped X-bracing, as featured on the Modern Deluxe Series, allows the top to breathe freely, enhancing resonance and sustain without sacrificing clarity.
Classic Standard Series details tie this bold new design to Martin tradition. Black binding outlines the gloss body, while the ebony fingerboard with abalone dot inlays keeps the look timeless. Nickel open-gear tuners with butterbean knobs provide smoothtuning, and the GE Modified Low Oval neck profile with high-performance taper ensures effortless playability across all 20 frets. Handcrafted in Nazareth, Pennsylvania, every detail honours the past while looking toward the future.
With its unprecedented size, booming low end, and cutting projection, the Super D-18 is more than a guitar — it’s a new benchmark in acoustic power. It’s built for players who need to be heard, whether leading a band or driving a room with nothing but a pick and their voice. This is Martin tradition amplified — crafted to carry your music further, louder, and stronger than ever before.
