Martin OMJM John Mayer Signature Rosewood Orchestra Electro Acoustic

John Mayer is one of the most gifted guitar players of his entire generation – not to mention his talent as singer/songwriter too! John Mayer had his pick of any guitar endorsement in the world, and he chose to play Martin because of their legendary reputation as exquisite guitar builders. This instrument was produced in collaboration with John himself, allowing the brand to produce an acoustic that was truly up to the high standards of his personal requirements. 

Made for Mayer

The OMJM model is a classic orchestral shape acoustic with a 14th fret neck joint. It’s perfect for strumming and finger picking. It also incorporates an in-built Martin pickup, delivering a premium-grade amplified sound in the process. The guitar provides a level of versatility that makes it suitable for just about any kind of contemporary music.
