In 1975, Roland welcomed the arrival of the first JC-120. A revolution in guitar amplifier technology, the JC-120 Jazz Chorus looked and sounded like no other amp. Thirty years later, the JC-120 remains in high demand by guitarists around the world. Unchanged from its original specification, the JC had attained legendary status by amp connoisseurs the world over. Now this rich heritage can be found in Roland’s full line of guitar and bass amplifiers — from the CUBE- to the AC- and D-Bass series.
