i LOVE chorus out front. flange is kind of a post distortion must for me. same with eq....though, eq can be used in a lot of interesting ways as you mentioned.
i recently bought another digitech 2101, and the way you can lay out all the effects is pretty awesome in that you can put them in any order......spiraling delays.........delayed reverb.......pitch shifted delay trails....theres some awesome, but for the most part, unusable tones you can come up with by linking stuff in different ways.
