Here’s something interesting to do with some of those 4049UB chips. It’s a CMOS Big Muff (22/7 being the fractional equivalent of pi). Brian from ROG added a switch to the tone stack to allow for flat response and a super scooped response, in addition to the classic scooped mids. I’ve also drawn up a version without that switch if you don’t want to mess with the extra wiring. Schematic and sound clips can be found on the ROG project page.
