[Used] BOSS CE-1 Chorus Ensemble Chorus Vibrato, Made in 1980-81, Guitar Effect Pedal. This is a used BOSS CE-1 Chorus Ensemble. It is in used condition. Contents: Main unit only. There are small scratches and dirt. There is slight rust and dullness on the metal parts. Sound output has been confirmed. The CE-1, created by extracting the chorus/vibrato section of Roland's ultra-classic guitar amp Jazz Chorus and unitizing it, is BOSS's first effector equipped with an analog BBD circuit and the world's first chorus pedal. This unit is characterized by its unique chorus and vibrato sounds, and the sound character of the built-in preamp is also attractive, making it a still-popular model.
