The classic! Has anyone ever built this thing?

Again, it was based on a circuit developed by me and a few friends back in the days when the NE570 was a "New" IC! The single transistor fuzz part of that circuit can be improved radically. Mine has "Big Muff"-type clipping stages, and sounds amazing.
