I know in 2001 they started making the CE-5 digital. I also know in general analog produces a warmer sound than digital. I have researched this on this site and others and I keep getting mixed answers. I am told that on this particular pedal that there is a major difference between the pre 2001 and post 2001 in sound.. But I also have been told that because of **HOW** they made the changes (Analog to Digital) to this particular pedal that it sounds virtually the same(In particular I guess what they altered and what they kept the same made it better than some analog to digital conversions).. Does anyone have the definitive answer on this? Thank you very much!
