For those of you that have the Super Ego, I've found that having a modulation pedal in the Ego's internal loop makes for some nice sounds. So far, I've tried several pedals in the loop, with mixed results. By far the worst was an Ehx Frequency Analyzer, (ring mod)- and the good ones have been phasers or flangers. But my absolute favorite is an Ehx C9 organ machine. With the Ego set for a long swell, the organ sounds seemingly come from out of nowhere, and just hang there. Having an EQD Rainbow Machine next in the chain just makes things even more out of this world.
