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.

The Nantel Verdict
The Nantel Verdict
Nearly 200 years of acoustic guitar building expertise in every instrument. The signature Martin tonal balance that sits perfectly in any musical context. Construction methods proven and perfected across generations of professionals. Solid wood tops that mature and improve in tone over years of playing.
Light gauge strings (.012s or lighter) let Martin's legendary scalloped bracing do exactly what it was designed for. Play this guitar every day and the top opens up beautifully - a Martin at one year genuinely sounds better than the day you bought it.
Martin has defined acoustic guitar since 1833 - nearly 200 years of wisdom in every joint. The signature voice is immediately recognizable on Nashville recordings, folk stages, and living room couches worldwide. Built for generations, these guitars genuinely sound better with age as solid wood matures. Owning a Martin isn't buying a guitar; it's beginning a musical relationship that deepens year after year.

OMJM 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.
