Boss CEB-3 Bass Chorus|Boss CEB-3 Bass Chorus is now part of! All the Boss pedals you love are still here, along with expert reviews of electric guitars, amps, and more.

Produces a spacious chorus effect without altering the natural sound of your bass guitar. A low filter lets you select the frequency band to which the chorus effect is applied. Stereo outputs and a Space Synthesis feature guarantee an optimum chorus effect every time. The CEB-3 started out as an anlog chorus using a BBD circuit but was later redesign with a new completely digital design. It is expected, but not confirmed, that the circuit change took place October 2001 at the same time that the CH-1 and CE-5 was redesigned.

Boss CEB-3 Bass Chorus

Assuming that the change date above is correct, you can spot an anlog CEB-3 by looking at its serial number. If the second letter, first number combination is P0 or earlier, the pedal is analog. This also means that all CEB-3s with pink labels are analog.
