Martin Guitar OMC-13E John Mayer Cutaway Acoustic Guitar

Martin OMC-13E John Mayer - Signature character for the Road Series!

With the OMC-13E John Mayer, Martin brings one of the best-known signature partnerships in the modern acoustic guitar world to the Road Series for the first time. The model combines John Mayer’s preferred playing specifications with a versatile OM construction, cutaway and stage-ready electronics. At its heart is a solid Engelmann spruce top paired with solid walnut back and sides. This gives the guitar a balanced acoustic foundation that combines warmth and clarity, making it well suited to nuanced fingerstyle playing as well as expressive chord accompaniment.

John Mayer’s preferred playing specifications

The 25.4-inch scale length is paired with a 1 11/16-inch nut width and a Performing Artist neck profile. This combination reflects John Mayer’s preferred specifications and gives the OMC-13E a familiar, direct feel. The cutaway provides easier access to the upper frets, while the ebony fingerboard, custom inlay and John Mayer signature make the close connection to the artist visible. Details such as the Antique White binding, faux abalone-style rosette and faux tortoiseshell pickguard also reflect the distinctive signature design.

Traditional Martin construction

Under the Engelmann spruce top is scalloped X-bracing made of spruce. The neck is joined to the body with a traditional dovetail joint, meeting the body at the 14th fret. The ebony bridge in the 1930 Belly style features a glued-in long white TUSQ saddle, underscoring the classic approach to construction. Open-gear nickel tuners and the slotted headstock complement the traditional design and create a deliberate contrast with the instrument’s modern stage readiness.

Designed for the stage and songwriting

With Martin E-1 electronics, the OMC-13E John Mayer is ready to connect directly to an amplifier, PA or recording setup. This means the guitar’s acoustic character is not limited to the living room, but can be easily brought into rehearsals, sessions and live performances. This combination of classic Martin construction, John Mayer’s preferred ergonomics and modern electronics makes the model a distinctive signature acoustic guitar within the Road Series.

A longstanding signature partnership

John Mayer’s collaboration with Martin dates back to the early 2000s and has grown into one of the manufacturer’s best-known artist partnerships. The OMC-13E John Mayer continues this tradition in a model that combines signature details with the more accessible Road Series. The custom fingerboard inlay featuring John Mayer’s signature and the pre-printed, signed paper label make the design’s origins immediately clear.
