The Martin OMJM 'John Mayer' Signature model is a refined, stage-ready acoustic-electric built to meet the demands of a Grammy-winning artist. A responsive Engelmann spruce top and East Indian rosewood back and sides give this Orchestra Model a lush, articulate voice with crisp treble, full bass and remarkable sustain. Hybrid scalloped X-bracing ensures dynamic tonal response and clear projection for fingerpicking or strumming, while the vintage-toned gloss finish evokes classic Martin aesthetics.

The select hardwood neck features a low-profile carve and 1.6875" nut width for fast, easy fretting, and 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 Natural I electronics offer natural-sounding amplified tone, making this an excellent choice for both studio work and live gigs, ideal for a discerning player after a signature Martin OM with a signed label and deluxe hardshell case.
