This 2026 Martin Custom Shop D-18 Adirondack Dreadnought Acoustic Guitar is in excellent condition. It has been very well cared for by its original owner although it does show a single fine weather check on the top just below the bridge (see picture). Otherwise, this guitar is in very clean condition and shows no dings, dents, scratches, or any obvious playwear. This guitar has been professionally set up and plays great! The neck is straight, the action is low and comfortable, and the frets are in excellent condition. This guitar will come complete with the original Martin Ply Hardshell Case that is also in very clean condition. Awesome deal on a fantastic playing and sounding Martin Custom Shop D-18 Adirondack!

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.
