The BOSS CEB-3 Bass Chorus is a pedal that was created with the bass player in mind.
Often bass pedals either kill or mud up the lows of the bass guitar, and us bass players love our lows, right?? right! That is why the CEB-3 is such a great bass chorus - it keeps the low end of your bass as you like it, while colouring the high frequencies with a rich and organic chorus effect. To gain this low end clarity use the low filter control knob. In combination of it with the Depth and Rate control knobs which let you set the chorus to be just as you want it, you're pretty much set to go.
As we wrote earlier, the BOSS CEB-3 is simply a great bass chorus pedal, point.
