The OMJM is a longtime signature staple in the Martin lineup, delivering expressive tone, smooth playability, and refined style—reflecting over two decades of collaboration with John Mayer. 

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.
