First introduced way back in 1975, the JC-120 Jazz Chorus is one of the
few guitar amps that can truly be called a legend. Rolands
long-standing flagship is universally recognized by pros as the
benchmark in clean guitar sound, and its rich tone and famous built-in
stereo chorus effect have been heard on countless popular songs over its
long history. Now celebrating 40 years of continuous production and
counting, the JC-120 remains the undisputed king of clean, and the
enduring choice of serious guitarists everywhere.
