alirght, I have EM and mxr clones and MXR has a little more woosh and less echo and EM is closer to a funky chorus. I can't get unity on the Mistress unfortunately. I left a thread on the maker's forum and everything else checked out for readings except 1 v ref resistor even though it's pin IS at voltage(less than .006 off) anywho, I say have all 3 be it diy or somehow you CAN afford a factory, they have their own flavor at the edges of the pots, the middle does overlap pretty closely like "all E Mistress in my head" thing. I know I'm guilty of that with chrous pedals, I have a semi modded small clone not stopping me from working on a CE-2!(thankfully both my mn3102's worked..)
