One hundred years of lacquer, perfected. The Custom Shop 0-18K2 CFM IV pairs a vintage gloss finish with striking all Flamed Koa and time-honored craftsmanship—a bold tribute to Martin innovation and the artistry beneath the surface.
A century ago, Martin changed the way its guitars were finished—embracing lacquer and setting a new standard for durability, beauty, and quality. The Custom Shop 0-18K2 CFM IV celebrates that milestone with a vintage gloss finish closely based on what Martin introduced in 1926—capturing the depth, warmth, and luster of those early instruments while reflecting the precision of today’s craft. Built with a striking solid Flamed Koa top, back and sides—an homage to the concert-sized all-Koa models that were the first to be sprayed with this lacquer finish—it blends tradition and innovation in every detail. From hand-shaped bracing to time-honored construction, it carries forward the same level of craftsmanship that defined Martin in the early twentieth century—and continues to shape it today. Limited to just 100 instruments, it’s not only a tribute to 100 years of lacquer, but to the enduring artistry beneath it.
