An effects pedal with chorus and vibrato functions. - Model Name: Chorus Symphony - Brand: behringer - Functions: Chorus, Vibrato - Control Knobs: Level, Chorus Intensity, Vibrato - Output Types: Mono, Stereo - Bottom: With non-slip pads Thank you for viewing. I purchased this around September of this year, but I am selling it because I obtained the original Boss CE-1. There is a scratch on the center of the back, from the time of purchase. I have confirmed the functions of the preamp, chorus, and vibrato, but my honest impression is that it's similar to the original, but different.
