The Martin Super D-18 propels the legendary Style 18 Dreadnought to new heights. With 20% more internal air volume than a standard Dreadnought, its Super D body offers deep, powerful bass, increased volume, and extended dynamics, while maintaining its iconic silhouette. The solid mahogany back and sides add warmth and impact, while the spruce top ensures clarity and projection. The forward-shifted, scalloped X-bracing, inspired by the Golden Era series and featured on the Modern Deluxe Series, ensures optimal response and power in every note. Refined finishes, such as black binding, abalone dot inlays, and a satin-finished neck, give it a classic look and exceptional playing comfort. Featuring an ebony bridge and fingerboard, the Super D-18 represents a bold evolution of an acoustic guitar icon, designed for musicians who want to be heard.
