Independent shopping perspective
The Korena take
Martin’s OM-45 is an Orchestra acoustic built with a solid Sitka spruce top, solid East Indian rosewood back and sides, and GE-scalloped spruce X-bracing. The GE Modified Low Oval neck has a High-Performance taper; its ebony fingerboard carries 20 Plek’d frets, with a 1-3/4-inch width at the nut. It is an acoustic-only instrument, so its role is centered on its unamplified setup. Pearl top and headplate details, Style 45 Hexagon fingerboard inlays, and gold open-gear tuning machines give the Natural-finish model its appointed look. A hardshell case is specified.

- Players seeking an Orchestra acoustic with solid Sitka spruce and East Indian rosewood construction.
