Martin Super D-18 #M3002052 Overview
The Martin Super D-18 pushes the classic Style 18 sound into bold new territory, giving you around 20% more internal air volume than a standard dreadnought. That extra space delivers a deeper low end, greater power, and a wider dynamic range, all while keeping the familiar Martin silhouette that players know and love. Genuine mahogany back and sides add warmth and definition, paired with a spruce top that ensures the clarity and projection you'd expect from a top-tier acoustic. Forward-shifted Golden Era scalloped X-bracing, inspired by vintage Martin voicing, keeps everything lively and responsive.
It’s also built for modern playability, with an ebony fingerboard, a GE Modified Low Oval neck profile, and a satin-finished neck that feels fast and comfortable. Tasteful appointments such as Old Style 18 inlays, black binding, and a tortoise-style pickguard finish off the understated aesthetic. If you're after a big, authoritative acoustic tone without losing classic character, the Super D-18 is a powerful evolution of the Martin tradition - perfect for players who want to be heard.

Full Description
View Full DescriptionBigger body, bigger voice
The Super D-18 takes the familiar dreadnought outline and pushes it further, offering around 20% more internal air volume for a noticeably bigger acoustic presence. That enlarged cavity adds thunderous bass, increased headroom, and an expanded dynamic range that responds effortlessly whether you're digging in hard or playing gently. It’s a bold step forward for players who love the Martin sound but want even more power and projection.
Classic mahogany character
Genuine mahogany back and sides give the Super D-18 its signature warmth, midrange punch, and vintage-leaning charm. These tonal qualities complement the massive Super D body by tightening up the low end and adding focus where it counts. You get a lively, open voice that suits strummers, flatpickers, and singer-songwriters who want a reliable, expressive tonal foundation.
Responsive Golden Era bracing
Using forward-shifted Golden Era scalloped X-bracing, the Super D-18 borrows structural and tonal cues from Martin’s most sought-after ’30s instruments. This bracing pattern boosts top movement, increases projection, and retains clarity even at high volumes. The spruce top benefits hugely from this voicing, giving you articulation and sparkle without sacrificing the massive low-end body the design is known for.
Modern feel with timeless style
With an ebony fingerboard, Old Style 18 inlays, and a satin-finished GE Modified Low Oval neck, the Super D-18 balances vintage inspiration with present-day comfort. The neck feels smooth and fast, while the subtle appointments keep the traditional look intact. Combined with a moulded hardshell case, nickel open-gear tuners, and a durable gloss body finish, it's a guitar built to perform and to last.
