The PI is the big, open sounding, gritty, grindy, fuzzy sustain for that 90s alternative sound like Dinosaur Jr., Mudhoney, Nirvana, Sonic Youth, etc.
I looked into all the late 70's Ram's Head and early 80s Black and Red muffs and noticed that they are very similar.
I believe this is a rare moment where there was some consistency in muffs.
I decided to go through all the versions and come up with one I felt had the best of all.
Similar to the 1976 Ram's Head I have offered in the past, the Pi has some slight differences.
The PI retains the huge, open grind
but I added a little more low end to give the tone a nicer feel. Chords have that classic wall of gritty fuzz and leads have a full, smooth grind.
