John Mayer’s signature Martin heads to the Road Series

Words by Mixdown

The OM-13E and OMC-13E put Mayer’s specs and styling into Martin’s more affordable range, with or without a cutaway.

John Mayer has had a signature Martin since 2003, but every one of them has been priced at the top end of the catalogue, well out of reach for most players. The new OM-13E John Mayer and OMC-13E John Mayer change that. They bring his specs and styling to Martin’s Road Series for the first time, and they’re his most affordable signature acoustics to date.

The partnership began with the limited-edition OM-28 John Mayer more than 20 years ago and has since grown to include the OMJM, which is still in Martin’s lineup today. The two new models borrow plenty from those guitars, starting with a solid Engelmann spruce top finished with an aging toner over solid black walnut back and sides. It’s the first time a Road Series guitar has had that top.

Both are built on Martin’s 14-fret Orchestra Model body, and the neck follows Mayer’s preferred measurements: a 25.4″ scale, a 1 11/16″ nut width and a Performing Artist profile with a standard taper. Antique white binding and a custom fingerboard inlay bearing his signature take care of the looks, with a pre-printed signature on the paper label inside for good measure. Both come fitted with Martin E1 electronics for plugging in, and each guitar ships in a softshell case.

The difference between the pair comes down to the cutaway and the trim. The OM-13E keeps the traditional non-cutaway body and bold herringbone around the top, a setup Martin pitches at fingerpicking, strumming and songwriting. The OMC-13E adds a cutaway for easier access to the upper frets, which makes it better suited to lead work, and swaps the herringbone for a multi-stripe top trim. Both also come in left-handed versions.
