Built for players who want massive acoustic tone and classic Martin craftsmanship, the Martin Super D-18 Acoustic Guitar takes the iconic D-18 formula and supersizes it for even more power and projection. Its enlarged Super D body design offers roughly 20% more internal air volume than a traditional dreadnought, delivering deeper bass response, greater volume, and an incredibly rich dynamic range.

A solid spruce top paired with genuine mahogany back and sides gives this guitar the legendary Martin balance of warmth, punch, and clarity, while forward-shifted Golden Era scalloped bracing adds responsiveness and resonance. The ebony fingerboard and bridge, GE Modified Low Oval neck profile, and satin-finished neck provide a smooth, comfortable playing experience that feels equally at home on stage, in the studio, or around a campfire.

With its bold low end, powerful projection, and timeless Natural finish, the Super D-18 is a modern evolution of a classic acoustic cannon — perfect for flatpickers, singer-songwriters, and anyone looking for that unmistakable Martin sound with even more room-filling presence.

Comes with a Martin hardshell case.
