Independent shopping perspective
The Korena take
The OMJM 20th Anniversary is a right-handed, six-string acoustic-electric built in the 000 14-fret format. It combines an Engelmann spruce top with East Indian rosewood back and sides, then adds Fishman Gold Plus Natural I electronics for amplified use. Its mahogany neck has Martin’s low-profile, standard-taper profile, with an ebony fingerboard and bridge completing the layout. Made only in 2023 to mark 20 years of the OM-28JM model, it arrives with a hardshell case.
