Martin's Road Series receives its first John Mayer Signature Artist Edition with the OM-13E, bringing the tonal blueprint and performance specs of one of the most recognisable acoustic partnerships to a wider field of players. A solid Engelmann spruce top treated with aging toner pairs with solid black walnut back and sides, a combination that delivers responsive dynamics and balanced frequency response across the midrange and low end. The 000 14-fret body with scalloped X-bracing provides articulate projection and rich harmonic detail, while bold herringbone purfling, antique white binding, and a custom fingerboard inlay bearing Mayer's signature complete the visual signature.
The 25.4" scale length and 1 11/16" nut width follow Mayer's preferred specifications, matched to a Performing Artist neck profile in select hardwood with satin finish for smooth position changes. The ebony fingerboard extends to 20 frets, complemented by an ebony bridge fitted with a white TUSQ saddle and nickel open-gear tuning machines. Martin E1 electronics provide amplified output with onboard tone shaping, while the faux tortoise pickguard protects the spruce top during performance. A softshell case is included for transport and storage.
