Distinctive lush chorus, amazing vibrato, the Retro-Sonic Chorus Ensemble is the only true reproduction of the 1976 CE-1 using the original analog BBD. Its lush, focused tone is the standard by which all other chorus effects are measured. The Chorus Ensemble is capable of a wide range of sounds from analog chorusing to pulsating vibrato, having the unique Vibrato feature that was incorporated on the original which simulates a Leslie rotating speaker. The chorus and vibrato functions are selectable through a footswitch control, allowing desired presets to be maintained by separate control. The Mono an Stereo outputs allow for a two amp setup for an amazing chorus experience. The unit features hi grade components, true bypass, and now powered by 9VDC, (thanks to a custom power chip) there's no need for a special adapter, just plug into your existing rig and enjoy!
