I've been chatting to another Bossarea person about chorus pedals and some of the differences between CE-2 and CE-3, analog and digital, etc.
Now I have a CE-2 and I love it but I also have a CE-20 and love that too (nut not as much as my CE-2)!
The CE-20 models the Dimension D (SDD-320?) and CE-1 but I wasn't sure how close it got with the COSM model. Anyone out there with these pedals and some thoughts to throw in?
A CE-2 won't be quite like a DC-2 or DC-3, apart from the general similarities of delay in that time range.
The dimension units use out-of-phase cancellation to diminish or remove the more audible pitch bending associated with chorus -- so you end up with the doubling portion of the effect more or less by itself.
With a chorus effect, the pitch bending is necessary to provide the delay between the singular wet and dry signals.
Sometimes I like to put the DC-3 after the CE-2 to create the effect of the CE-2's knobs going up to "11" or "12", in the Spinal Tap sense -- it adds additional width/depth for some really thick chorus without too much pitch bending.
I should rephrase that -- the pitch bending is necessary to provide the "movement" of the delay that produces the chorus sound. A static delay time between wet and dry signals won't do it.
I think that in the case of dimensioning, there are two wet signals working on the dry one, but they interact with one another in such a way as to cancel out the points in time where the LFO's movement produces more audible pitch bending.
