This is the new for 2026 Martin Super D-18 in Natural! The Martin Super D-18 expands on the legendary Style 18 Dreadnought with a larger-than-life design. With 20% more internal air volume than a standard Dreadnought, this Super D body offers thunderous bass and unmatched projection. A solid spruce top, paired with solid mahogany back and sides, delivers rich overtones and a complex sound that will only open up over time. Forward-shifted Golden Era scalloped X-bracing, as featured on the Modern Deluxe Series, delivers vintage-inspired tone and sustain, while appointments like classic Multi-Stripe top inlays and Old Style 18 dot inlays showcase timeless Martin style. Complete with nickel open gear tuners and a dovetail neck joint, the Super D-18 is a bold evolution of an acoustic iconbuilt for players who want to be heard!
