The original Boss chorus sounds of the 1970s are reborn with the CE-2W. It's "standard" mode faithfully recreates the classic CE-2 chorus sound, and adds an expansive new sound field with stereo output (which was unavailable in the mono CE-2). The CE-1 mode fully reproduces the stereo chorus and vibrato sounds of the legendary CE-1, with the addition of variable chorus depth not available in the original pedal. All analog circuitry with bucket-brigade (BBD) delay line; made in Japan.
