For players and fans looking to capture the voice of an artist equally comfortable in the worlds of pop and blues, the Martin OM-45 John Mayer 20th Anniversary Signature delivers on that promise with unmatched tone and elegance. Crafted to commemorate two decades since the release of Mayer’s original OM-28JM, this Platinum-anniversary edition takes everything to the next level with exceptional tonewoods, luxurious upgrades, and a design that is both player-focused and collector-worthy. Its Engelmann spruce top offers articulate clarity, while the Guatemalan rosewood back and sides provide deep, resonant warmth. Paired with scalloped X-bracing and a dovetail neck joint, this guitar responds with lively projection and sustain, ideal for strumming and fingerstyle playing alike.

The genuine mahogany neck is carved to Mayer’s specifications, featuring a Low Profile shape with a slightly thinner 1-11/16" nut width for exceptional comfort and playability. An ebony fingerboard and 25.4" scale length allow effortless fretting, while the custom inlays and fine silver binding around the fingerboard, bridge, pickguard, and headplate add a stunning visual signature. Additional premium features include a compensated bone saddle, antique white binding, and satin nickel Waverly tuners. A custom label signed by John Mayer himself and a molded hardshell case complete this remarkable instrument, making it a must-have for serious collectors and tone connoisseurs; available now at Haggerty’s Music.
