About This Guitar
The Martin OMJM John Mayer is a signature Orchestra Model that reflects over two decades of collaboration between Martin and one of today’s most influential guitarists. Based on Mayer’s original OM-28JM, this model brings together refined tonewoods and thoughtful design choices in a more widely available format while maintaining the core character of the original.
With an Engelmann spruce top paired with East Indian rosewood back and sides, the OMJM delivers a balanced and expressive voice with clarity, warmth, and dynamic range. The 25.4" scale length adds projection and headroom, while the Low Profile neck offers a smooth, comfortable feel across styles. Appointments like bold herringbone trim, an abalone rosette, and custom inlays—including John Mayer’s signature—round out a design that feels both classic and personal.
