The Martin OMJM John Mayer Anniversary Custom Artist Limited Edition Acoustic Guitar is a remarkable instrument crafted in collaboration with John Mayer to celebrate the 20th anniversary of his popular OM-28JM model. This tasteful Orchestra Model (OM) guitar embodies versatility, contemporary musical styles, and superior craftsmanship. The guitar comes with a unique label bearing Mayer's electronic signature, and its availability is limited to the calendar year 2023.

Mayer's influence and Martin's expertise converge to create a stunning and captivating guitar. The OMJM John Mayer Anniversary model is an acoustic-electric guitar that showcases meticulous design enhancements and top-tier tonewoods. With Fishman Gold Plus Natural I electronics onboard, this instrument is ready to deliver its formidable tone both plugged in and unplugged.

Constructed with a Engelmann spruce top and East Indian rosewood back and sides, the OMJM resonates with lush sound, impressive projection, and exquisite note separation. The guitar's body benefits from Martin's 1/4-inch scalloped X-bracing pattern, which contributes to its voluminous projection.

The neck of the OMJM offers a mahogany construction with a standard taper and a thinner 1-11/16-inch width at the nut, providing a comfortable and quick-playing experience. The ebony fingerboard, embellished with 20 frets and custom inlays, complements the guitar's aesthetics and playability. An ebony bridge, nickel open-gear tuners, and compensated white TUSQ saddles ensure excellent intonation and reliability.

The OMJM John Mayer Anniversary guitar features Fishman's Gold Plus Natural I system, which boasts exceptional sensitivity and dynamic range. This system accurately captures the vibration of the strings as well as the top of the instrument, ensuring a well-balanced and accurate amplified sound.

With a unique label bearing Mayer's electronic signature, this limited-edition guitar is a testament to the enduring partnership between John Mayer and Martin Guitars. It commemorates Mayer's legacy and musical artistry, making it a must-have for collectors, enthusiasts, and players who appreciate premium craftsmanship and outstanding tone.
