All About Roland’s Legendary Jazz Chorus Guitar Amp.
The JC Jazz Chorus series was born in 1975 and was loved by some of music’s biggest names. To this day the JC series is still evolving as a cutting edge product. From the time it was first manufactured back in 1975, the JC-120 was, and still is, aimed at a totally different sound from the warm distortion sound of the standard tube amp. Early on, the solid and straight “JC Clean” sound was not so attractive to some musicians who loved the good old tube distortion. Gradually, however, the transparency and pureness of the “JC Clean” sound was found to be irreplaceable by many guitarists. With its incomparable tone and professional durability the Jazz Chorus series has consistently been around throughout the evolution of music from the time of its debut. It has never been stuck in the past and continues to provide solutions for the changing musical scene from the recording studio to the live stage.
The unique “JC Clean” has a wide-range, pure, and solid sound with fat sound pressure and a crisp response. The Jazz Chorus is also known for being the amp which utilizes the full potential of effect pedals because it faithfully regenerates input signals. The “JC Clean” tone is achieved by a “clean sound specialized design” manifested by JC’s dual speakers and dual power amps. These dedicated amps drive the speakers to their full potential resulting in clarity and high definition without loss. It brings about not only fat sound pressure but pureness of the tone and a dynamic response with voluminous headroom.
The JC chorus effect is also the result of its specialized design. By using two dedicated power amps, one of the two speakers plays the direct tone, and the other speaker generates the tone with periodic pitch modulation. These two tones are mixed in aural space creating the beautiful chorus sound. The characteristic sound produced by this unique design is called “Dimensional Space Chorus”. This is the world’s first Chorus effect which made its debut onto the music scene with the launch of Roland’s JC-120 Jazz Chorus back in 1975.
