The D-18 Modern Deluxe is a powerful mix of classic Martin style and modern innovations. Vintage-style features include a Sitka spruce Vintage Tone System (torrefied) top, a dovetail neck joint, and natural protein glue construction. The look is unlike anything in Martin's production line to date, with East Indian rosewood binding, stylish gold frets, gold open‐gear tuners, and a 1930s style script logo inlaid in pearl on the headstock. Modern features include liquidmetal bridge pins with red dots and a carbon fiber bridgeplate that boosts volume without adding weight. The new neck shape is designed for maximum hand comfort up and down the fretboard.
