The OMJM John Mayer is a long-running signature model on Martin's 000 body at the 25.4" scale. East Indian rosewood back and sides sit under an Engelmann spruce top in Antique Toner, braced in scalloped X, with bold herringbone around the top, an abalone rosette, a zig-zag back strip and custom mother-of-pearl inlays on ebony. The neck is a Low Profile shape with a Standard Taper, and the electronics are a Fishman Gold Plus Natural I.
The nut is 1 11/16", against 1 3/4" on the other OMs here. That brings the strings slightly closer together and makes chord shapes in the first position a smaller reach. For the same body and woods with the wider nut, look at the OM-28E, and for an unplugged OM, the OM-28.
