The Martin Super D-18 Acoustic Guitar takes everything players love about a classic mahogany dreadnought and expands it into something bigger, bolder, and more powerful. Built with a Super D-14 fret body that offers roughly 20% more internal air volume than a traditional dreadnought, this guitar delivers a commanding low end, increased volume, and an impressive dynamic range that fills the room with ease. A solid spruce top provides crisp articulation and projection, while the genuine mahogany back and sides add warmth, punch, and that unmistakable woody character players chase for a lifetime. Available at Haggerty’s Music, this is a guitar that immediately feels familiar—but sounds larger than life.

In your hands, the Super D-18 responds with a lively, expressive voice thanks to its forward-shifted Golden Era scalloped X-bracing, designed to maximize resonance and responsiveness. Whether you’re digging into aggressive flatpicking or easing into delicate fingerstyle passages, every note blooms with clarity and power. The GE Modified Low Oval neck with High-Performance Taper offers a smooth, fast feel that accommodates a wide range of playing styles, while the ebony fingerboard and bridge add durability and a refined tonal edge.

Visually, it stays true to its roots with understated elegance—an aging toner spruce top, classic Style 18 appointments, black binding, and clean abalone dot inlays give it a timeless, workhorse aesthetic that never goes out of style. Paired with a protective hardshell case, the Super D-18 is ready for the stage, studio, or anywhere your music takes you. Available now at Haggerty’s Music, this guitar isn’t just an evolution of a legend—it’s a statement piece for players who want to be heard and felt.
