The Spanish cedar neck with diamond volute is carved with playing comfort in mind, combining 1-11/16" width and low profile shape for easy fretting. The East Indian rosewood headplate sports Martin’s Old Style decal in silver rather than the familiar gold (another nod to the OM-28JM John Mayer Signature Edition) and nickel Gotoh opengeared tuners with butterbean knobs. The black African ebony fingerboard highlights 1/8” mother of pearl position markers at the 5th, 7th (two), 9th, 15th and 17th frets, a unique 12th fret position marker of two dots flanking a slotted square, and John Mayer’s signature inlaid in mother of pearl between the 19th and 20th frets.

Style 45 white bridge pins and endpin are inlaid with abalone dots. The black African ebony bridge is fitted with a compensated TUSQ saddle, which combines with the factory-installed Martin Gold Plus Natural electronics for accurate, natural amplified sound. Adding to the beauty of this instrument is the flawless finish; vintage toner on the top, polished gloss nitrocellulose lacquer on the body and polished gloss on the headplate.

To provide a touch of his personal style to the OMJM John Mayer Special Edition guitar, John Mayer has created a unique art deco-inspired monogram, which is embroidered on the special vintage Geib style hardshell case. Each guitar in this open series bears an interior label imprinted with the signatures of John Mayer and Martin Chairman C. F. Martin IV, and individually numbered in sequence.
