Martin OMJM John Mayer w/case

The OMJM blends Martin’s long history of OM-style acoustics with John Mayer’s preferred feel, response, and tonal balance. Built with an Engelmann spruce top and East Indian rosewood back and sides, it delivers a warm, articulate voice with a fast attack and a sweet upper register—exactly the character Mayer is known for onstage and in the studio. The neck features Martin’s Low Profile carve with a Standard Taper, making it one of the most approachable and comfortable OM models in the lineup. Premium appointments such as the Bold Herringbone top trim, abalone rosette, and custom inlays distinguish it as a signature instrument while preserving the refined look of a classic Martin.

With its responsive top, balanced projection, and unmistakable Mayer-inspired voicing, the OMJM remains one of Martin’s most versatile artist models—ideal for fingerstyle, strumming, and everything in between.
