From the post
A contribution drom Jordan Fontaine, sort of a Big Muff on steroids...
t's a Big Muff with a bass booster that can be blended in between Q2 and Q3. The overload of low end and volume freaks out Q3. The circuit goes from fairly standard muff to sputtering and gated goodness. I find Sustain and Overload both set around 1 or 2 o'clock gets the best sound. The tone stack is fairly flat. The Mid Shift switch gives back some of the standard scoop and makes full CCW much darker for doomy sounds. The switch ends up being fairly subtle and can easily be omitted.
The build is verified by both my build and Fuzzonaut who gave it good review.
