The Martin OMJM John Mayer Signature model is a refined, stage-ready acoustic-electric built to meet the exacting standards of a Grammy-winning artist. Featuring a responsive Engelmann spruce top and East Indian rosewood back and sides, this Orchestra Model delivers a lush, articulate voice with crisp treble, full bass, and remarkable sustain. Hybrid scalloped X-bracing ensures dynamic tonal response and clear projection whether fingerpicking or strumming, while the vintage-toned gloss finish evokes classic Martin aesthetics. Designed for comfort and performance, the select hardwood neck features a low-profile carve and 1.6875" nut width for fast, easy fretting. The solid ebony fingerboard is adorned with mother-of-pearl inlays and John Mayer’s signature at the 20th fret. Factory-installed Fishman Gold Plus electronics offer natural-sounding amplified tones, making this an excellent choice for both studio work and live gigs. With a signed label, deluxe hardshell case, and timeless OM body shape, the OMJM is an exceptional instrument built for discerning players.
