Boss CE-1 Chorus Ensemble

The Boss CE-1 Chorus Ensemble was a chorus pedal used by Mike Rutherford and Tony Banks.

Mike Rutherford's Boss CE-1
Mike Rutherford started using the Boss CE-1 Chorus around the time of Wind And Wuthering in 1976. In one interview he talk to A Trick Of The Tail. as stated in an interview, as the CE-1 was released in June 1976 which as after its release).

Tony Banks' Boss CE-1
The Boss CE-1 was one of Tony Banks' key effects devices on his keyboards during the late 1970s, to add thickness and depth to their sound. He began using it as early as the Wind And Wuthering album & tour on the RMI Electra 368, replacing the Leslie speaker. He later liked using the CE-1 on the Yamaha CP-70, and also the Hammond T-102 organ with an MXR Phase 100 to simulate the Leslie rotating speaker sound.

Around the time of Duke & Abacab, Tony seemed to prefer the MXR MX-134 Stereo Chorus for most other synths but continued to use the Boss on the CP-70 for a straight mono sound live. Most Genesis tour programs from around the early 80s list the generic 'MXR/Roland and Boss effects pedals' for Tony, which implies he probably did have the Boss Chorus around.

Peter Gabriel's Boss CE-1
Like Tony Banks, Peter Gabriel used a Boss CE-1 Chorus on his Yamaha CP-70 during the Scratch tour in 1978 to achieve the distinctive chorused sound to be heard on records to come. Around the time of making Security, it appeared he had two CE-1's, both of which are seen on top of the Fairlight CMI in footage from the South Bank Show. He continued to use the CE-1's during the So album recording and tour, alongside the newer Boss CE-3 Chorus. And at least on the Passion soundtrack.
