The Martin Super D-18 takes the classic dreadnought into a whole new league. Built with Martin’s largest body size yet, this acoustic guitar moves more air than a traditional dreadnought and delivers noticeably more volume, depth, and projection. With a solid spruce top and genuine mahogany back and sides, the Super D-18 produces a powerful, focused tone that feels big without ever losing clarity or control.

From a player’s perspective, this guitar responds with very little effort. The forward shifted Golden Era scalloped X bracing lets the top breathe, giving you strong fundamentals, long sustain, and a wide dynamic range that works beautifully for flatpicking, strumming, and driving rhythm work. Spruce brings articulation and cut, while mahogany adds warmth and punch through the midrange, making this Martin dreadnought both authoritative and musical in any setting.

Visually and ergonomically, the Super D-18 stays rooted in Martin tradition. The gloss body, black binding, ebony fingerboard with abalone dots, and open gear tuners give it a timeless look, while the GE Modified Low Oval neck with high performance taper keeps it comfortable all the way up the neck. Handcrafted in Nazareth, Pennsylvania, this is a professional grade acoustic guitar built for players who want maximum headroom, bold projection, and classic Martin tone in a modern, larger format.
