Martin Custom Expert D-18 1937 Sinker Mahogany Acoustic Guitar

The Martin Custom Expert D-18 1937 Sinker Mahogany Acoustic Guitar channels the bold sound and spirit of a pre-war dreadnought into a modern masterpiece. Featuring a sinker mahogany back and sides paired with an Adirondack spruce top, this limited-edition build delivers punchy lows, clear mids, and a shimmering top end with remarkable balance and projection. The forward-shifted scalloped X-bracing enhances responsiveness, while the vintage gloss finish and aging toner add timeless character that will only grow deeper as the guitar matures.

Built with Authentic Series specs, this Custom Shop gem incorporates hide glue construction, a dovetail neck joint, and the iconic D-18 Authentic 1937 Barrel & Heel neck profile with a standard taper. Nickel Waverly tuners, faux tortoise appointments, and abalone inlays add period-correct detail, while the included ply hardshell case keeps your investment safe. Limited to only 50 instruments worldwide and available exclusively through Custom Shop Expert Dealers, this D-18 is a rare opportunity for players and collectors seeking vintage-inspired tone and craftsmanship at its finest.
