Martin Custom Shop 0-18K2 CFM IV Limited 24/100

Weight: 3.5 lbs 

DESCRIPTION

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 body—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.

INDIVIDUALLY PHOTOGRAPHED

After 15 years of innovation in our photography process, Ish Guitars has developed a way to get you the most accurate true-to-life color of every instrument we sell. We never embellish, oversaturate, or misrepresent our images, so that your buying experience can be as much like visiting our showroom as possible. Keep in mind that various computer screens can show colors a bit differently, so the color on your screen may not match the real thing perfectly no matter how hard we try. Also, unless otherwise noted, we individually list and photo every piece of gear that comes through our doors.
