Tweakazound sound-design has made lot of instruments but not that many effects.
But lately I've been into the effect side as well. Here's a combi I did for use as a master suite. Make sure that you don't have too loud signal going in or it won't sound as good - the levels around -4db is about right. Try the 3rd knob which is an exciter kinda effect - tweak it til you think it sounds the best.
