Stay away from the Moog EP-2 Expression Pedals. They are good solid pedals and work great with the moogerfoogers and i'm sure other things as well, so i'm not dissing them at all, but they do not work well with the timefactor or modfactor. I think its because the EP2's range is from -5v to +5v CV and i think the eventides only use 0-3v, so the range of motion that had any effect on the eventides was tiny and useless. I'm thinking about trying the Boss FV-500's. They look solid and dependable. So many of the other options look so cheap. hope this helps. Anyone have any other suggestions?
