Classic Vintage Voice Refined with Modern High-Tech Precision

The Guitar Sanctuary is proud to offer the Martin D-18 Modern Deluxe Mahogany Dreadnought. Designed for players who demand the dry, punchy vintage character of a pre-war 14-fret dreadnought combined with modern ultra-lightweight structural engineering, this instrument pushes acoustic performance into a new class.

Sanctuary Expert Note: "The Modern Deluxe series is a revelation for flatpickers and acoustic purists. By combining a VTS torrefied top with a carbon fiber bridge plate and Liquidmetal pins, Martin gave this D-18 noticeable volume gains and immediate, broken-in vintage warmth without sacrificing the fundamental clarity mahogany is famous for."
