Sweet build. I happen to like the double muff for its simplicity. It’s an OD and distortion in one, not really a fuzz but you can argue fuzz since the clipping happens in the transistors. I’m sure if you put a BMP tone stack after it it would make it more fuzzy
I like the double muff as well. If you look at the schematic, if I recall correctly, I believe it has roots in the fuzz face topology albeit very modified.
