I played around with my perfboard version yesterday for quite a while. I love the sound of this circuit going into the egodriver. It really makes the ego cut and sustain like a cranked amp IMO (i've always thought that a cranked amp brings out more mids anyway and most pedals just seem to push too much 700hz and above while this pushes 400hz etc...). I think i'm going to try the timmy as well and see how it likes this type of pairing.
I'm building up a fat>ego pedal to demo with a band tonight actually, we'll see how it goes.
