The Custom Shop D-18 brings top-shelf tonewoods and handcrafted Martin quality within easy reach. Built with solid genuine mahogany and an Adirondack spruce top, it delivers clear, punchy tone with powerful projection-perfect for flatpicking, strumming, and everything in between. Hand-shaped Golden Era scalloped forward-shifted bracing and a traditional dovetail neck joint give it vintage-inspired resonance and dynamic response, while faux tortoise binding adds a unique twist on Style 18 tradition. It's a special addition to our lineup that offers the full Custom Shop experience-no design session required. Whether you're stepping up to your dream guitar or adding something truly inspiring to your collection, the Custom Shop D-18 proves that high-end craftsmanship doesn't have to be hard to find.
