The Martin Custom Expert 000-18 1937 Sinker Mahogany is a rare Custom Shop creation that pays tribute to the golden era of acoustic design. Sinker mahogany back and sides paired with an Adirondack spruce top deliver warm, woody mids, sparkling trebles and a balanced low end with impressive clarity, and the smaller 000 body size enhances articulation and responsiveness, ideal for fingerstyle, vocal accompaniment and players seeking intimate tonal detail.

Built to authentic 1937 specifications, this guitar features forward-shifted scalloped X-bracing, a dovetail neck joint with hide glue, and a vintage gloss finish that radiates timeless character. The D-18 Authentic 1937 Barrel & Heel neck profile with standard taper provides a comfortable, historically inspired feel, while abalone inlays, tortoise-style binding and Waverly nickel open-back tuners complete the vintage aesthetic. Limited to just 50 guitars worldwide, this 000-18 is a masterful blend of heritage, craftsmanship and collectability.
