Finally I got one! Beautiful and rare toy - only 10 pedals like these were made in green sparkle color. I guess most of the people are already know it as an extra expensive effect with tiny and low cost circuit But I still like and recommend it. Got tons of lows but the Pinch control helps to cut mud out. Along with gate it adds compression and mid-hump to my ears. Fully clockwise gives you a synthy sound. Wool adds distortion even too much, I never dime it, but its just cool to know that if you need to make a little earthquake right here and now - you can do it Really dig how it acts with tube amps , it blends with theirs dynamics and even dirt.
