Boss CE-1 Chorus Ensemble

produced: 1976 to mid-eighties

Boss CE-1 Chorus Ensemble, 1979

The first officially sold Roland pedal under the Boss brand name became a huge success and started off the long Boss pedal history. The CE-1 is based on a circuit which Roland used in their JC-120 Jazz Chorus amplifiers first released in 1975. It was the first effect pedal to utilize a BBD (Bucket Brigade Device) chip. Originally designed by Philips this IC had just been licensed to Matsushita and thus was available for mass production. The CE-1 is a mains powered unit that features both chorus and vibrato modes. They both use the same BBD circuit so it is impossible to use both at the same time. Stereo outputs were features not common in effects pedals at that time.
