Just received this fabulous pedal in the mail and spent a few minutes with it. Oh my god, my quest for a decent envelope filter if finaly over . Cool looking pedal also...But the most important thing, a very well balanced range which is probably the most difficult thing to get on a filter. Just two knobs, easy to dial in and...remember for an analog guitar player !! For the price (now that the canadaian dollar is catching up) one of my best buys in a long time.
