Really crank the low filter: 8:30 to 9:00. Now set level/rate/depth to taste: try 12:00 to start. Now play Free's "All Right Now". When you get to the guitar solo, the "bump ba bump ba bumpa bumpa" stays nice and clean but the "doo dah doo dah" part get a nice chorus that really emphasizes the difference. I just got the CEB-3. Anybody know any other good tricks?
