Independent shopping perspective
The Korena take
Built as a limited-edition six-string acoustic, the OM-45 John Mayer Platinum pairs a solid Engelmann spruce top with solid Guatemalan rosewood back and sides. Its scalloped Adirondack spruce bracing is described as allowing the top to move freely, supporting harmonic detail and sustain. The modified V mahogany neck, 1-11/16-inch nut width and 20-fret ebony fingerboard give chord changes and higher-register lead work a defined playing layout. A hardshell case is provided.
