Martin Super D-18

Martin Super D-18

The Martin D-18 has been one of the most trusted dreadnoughts in acoustic music for nearly a century — a no-frills workhorse with honest tone and legendary build quality. The Super D-18 takes that foundation and asks a simple question: what if there was more of everything? More bass, more volume, more dynamic range, more presence. The answer is a guitar that honors the Style 18 tradition while pushing it further than it’s ever gone.

Key Features:

• Super D Body with 20% More Internal Air Volume — A larger body than a standard dreadnought translates directly into thunderous low-end response, increased overall volume, and an extended dynamic range that rewards both fingerpickers and hard strummers
• Solid Genuine Mahogany Back and Sides — Warm, punchy, and focused, mahogany brings the midrange clarity and natural punch that has made Style 18 guitars the go-to choice for folk, bluegrass, country, and roots players for generations
• Solid Spruce Top — Delivers the crisp, clear projection and note definition that keeps the Super D-18 articulate even at high volume
• Forward-Shifted Golden Era Scalloped X-Bracing — The same bracing architecture featured on Martin’s Modern Deluxe Series, optimized for maximum responsiveness and power — every note blooms quickly and sustains fully
• Ebony Fingerboard and Bridge — Dense, smooth, and durable, ebony adds snap and clarity to the attack while providing a playing surface that feels refined and fast under the fingers
• Satin-Finished Neck — Smooth and comfortable for long playing sessions, with none of the drag of a high-gloss finish
• Black Binding and Abalone Dot Inlays — Classic, understated appointments that keep the aesthetic clean and timeless without distracting from the guitar’s voice
• Nickel Open Gear Tuners — Period-appropriate hardware with smooth, reliable tuning performance
• Hardshell Case Included
