The CE-5 is the 4th pedal in Boss Chorus Ensemble line. The major difference between the CE-5 and its predecessors is the additon of a level control and a high and low filter control. It has been in production for longer than any other chorus in the CE series but remained virtually unchanged until it received a major overhaul October 2001.

Version differences 

BOSS CE-5 Chorus Ensemble

There are 2 versions of the CE-5 where the second version is denoted CE-5A. This is printed on the PCB so it is easy to figure out which version you have. The first version is closely related to the CE-2 and CE-3. It uses the 1024 stage Panasonic BBD MN3007 and its associated clock driver 3101. The CE-5A is completely restructured. It uses surface mounted components and the BBD has been replaced with a digital design. All CE-5s made before October 2001 will have the old analog BBD circuit. The easiest way to determine which version you have is to use the serial number. If the second letter/first number combination is earlier than P1, you have the analog type. This also mean that all digital CE-5s will have a dark gray label.
