Martin OMC-13E John Mayer Signature Artist Edition Electro-Acoustic Guitar

Your next musical companion — expected January 2027

The Martin OMC-13E John Mayer brings John Mayer-inspired specifications to Martin's Road Series in a highly versatile cutaway electro-acoustic. Combining a solid Engelmann spruce top with solid black walnut back and sides, it delivers a responsive, balanced acoustic character with warmth, clarity and definition.

The cutaway body provides easier access to the upper frets, while a Performing Artist neck profile, 25.4" scale and 1 11/16" nut width create a smooth, familiar playing feel. Martin E1 electronics make it ready for live performance, and a Martin softshell case is included.

What Makes the Martin OMC-13E John Mayer Special?

The OMC-13E takes the character of a John Mayer Signature Artist Edition and combines it with the practicality of a modern Road Series instrument. Its solid Engelmann spruce soundboard uses an aging toner and scalloped X-bracing, paired with solid black walnut back and sides for a responsive voice designed to balance warmth, clarity and rich acoustic detail.

Where the OMC-13E particularly stands apart is its cutaway body, giving players easier access to higher positions on the fingerboard. John Mayer-inspired details continue through the Performing Artist neck profile and custom signature fingerboard inlay, while antique white binding and nickel open-gear tuners complete its distinctive appearance.
