In 1926 Martin switched its finishing over to lacquer, and the Concert-sized all-koa models were among the first guitars to be sprayed with it. A hundred years on, the Custom Shop 0-18K2 CFM IV is built in the image of those guitars, and Martin made 100 of them.
It's a 0 body joined at the 12th fret, in solid flamed koa top, back and sides, with a koa headplate to match. The Vintage Gloss finish is closely based on that original 1926 lacquer. Underneath, hand-shaped GE scalloped X-bracing.
The neck is a GE Modified Low Oval with Martin's High-Performance Taper, 1 3/4" at the nut on a 24.9" scale, set with a dovetail joint. Ebony fingerboard with abalone Old Style 18 inlays, ebony bridge, bone nut and saddle, and Golden Age Relic Brass tuners on a slotted headstock wearing the Martin O'ahu script.
Each one carries a "100 Years of Lacquer" paper label with Chris Martin IV's printed signature, numbered out of 100. Ships in a Martin hardshell case.
