What effect do you use the most? I bought an ART ECC primarily to use to decide what kind of effects I like so I can buy appropriate individual units later but now I'll I've realized is that I can find uses in various songs for a lot of different sounds. I think that the one I would be most lost without though would be my flange, I dig that swirl. I have finally found a really practical use for the switchable EQ on my amp though. Heavy flange type effects punch through the mix much better with an extreme W shaped EQ.
