Description

This limited-edition Custom Shop D-18 brings the power and punch of a 1937-style Dreadnought to life with rich, resonant sinker mahogany and a responsive Adirondack spruce top. Built with Authentic 1937 bracing, a hide glue dovetail neck joint, and an adjustable truss rod, it’s crafted for serious tone and long-term playability. The vintage gloss finish adds to the old-soul vibe—and its voice only deepens over time. Limited to just 50 guitars, this is a bold, vintage-inspired build made for players who crave character and clarity.
