Martin Custom Shop D-18 1937 Authentic Sinker Mahogany

Serial: 2983302

The Martin Custom Shop D-18 1937 Authentic Sinker Mahogany is a faithful, high-end tribute to one of the most revered dreadnoughts ever built, elevated further by the use of rare sinker mahogany back and sides. Designed around Martin’s 1937 Authentic platform, this guitar delivers a powerful, dry, and incredibly responsive voice with the depth and complexity that only old-growth tonewoods and traditional construction methods can provide.

Sinker mahogany, reclaimed from riverbeds after decades of natural aging, brings added density, warmth, and harmonic richness to the classic D-18 sound. Paired with an Adirondack spruce top and Authentic-era bracing and construction techniques, this Custom Shop build offers explosive headroom, strong fundamentals, and a woody, vintage character that excels for flatpicking, strumming, and traditional acoustic styles.
