AUSTRALIA'S #1 ACOUSTIC GUITAR SPECIALIST
AUSTRALIA'S #1 ACOUSTIC GUITAR SPECIALIST
40/LE-OM45JM-20TH
The limited-edition Martin OM-45 John Mayer Anniversary model celebrates two decades of artistic collaboration between John Mayer and Martin Guitars. Built in extremely limited numbers, this collector-grade instrument combines the luxurious craftsmanship of the OM-45 platform with custom Mayer-designed aesthetics. A gloss-finished Engelmann spruce top and richly grained Guatemalan rosewood back and sides give it a powerful yet articulate voice, equally suited to expressive fingerstyle or dynamic strumming.
Genuine silver trim on the headplate, pickguard, fingerboard and bridge makes the OM-45 John Mayer Anniversary visually striking and unmistakably refined. A mahogany neck with a comfortable Modified V profile and a 1-11/16" nut width keeps playability streamlined, while the ebony fingerboard with abalone and mother-of-pearl inlays adds both feel and presence. Satin nickel Waverly open-gear tuners, scalloped X-bracing and a bold Gray Sunburst finish make this an instrument ideal for collectors and John Mayer fans balancing tone, artistry and legacy in one guitar.
