Martin OMJM John Mayer Acoustic-Electric Guitar

The OMJM John Mayer brings together signature style and stage-ready tone in a guitar designed with one of Martin’s most iconic modern artists. Based on Mayer’s original limited-edition OM-28JM, this Orchestra Model blends many of the same high-end features with wider availability and a more accessible price point—much like the 000-28EC did for Eric Clapton fans. With an Engelmann spruce top and East Indian rosewood back and sides, it delivers a balanced, expressive sound that’s perfect for today’s wide range of musical styles. It features a long 25.4" scale length for added projection, a Low Profile neck for smooth playability, and elegant details like bold herringbone trim, an abalone rosette, and custom inlays—including John’s signature on the fingerboard. Optional Fishman® electronics make it a versatile performer, and it comes with a hardshell case. Whether you’re a longtime fan or just love a finely crafted OM, the OMJM is a tribute to more than two decades of collaboration between Martin and one of the most influential guitarists of his generation.
