I used to love f*kin around with SynthEdit back in the '98 days. Of course, it was just an experiment back then, but if you look at some of the more creative plugins today, a lot of them have been made with SE. (I have no facts to back that up.)
Anyway, when I was into it, I made "noun_verb": a reverb, modulated delay, limiter/saturator.
+It has separate delay lines that can be ganged or separate
+Delay time is something like 1 sample to 5 seconds (a divide setting helps with fine control)
+Delay feedback has a lowpass control
+Low delay times and some modulation make for a nice flange effect
+Asynchronous limiting/saturation (separate control for low and high limit)
I think it's a pretty good effect.
If you want to dl it, go here:

Enjoy.
