I agree. But, back about 100 years ago when I was just a grasshopper, a Big Muff Pi was a Wonderful Thing. Amps equipped with master volumes were kinda thin on the ground, so if you wanted to sound like you were killing your amp/speakers at low volume you needed some kind of wicked distortion box. The Univox "Fuzztone" was one way of doing it, but they were so over the top and noisy it was ridiculous. Think "Satisfaction" from the Stones, or Norman Greenbaum's "Spirit in the Sky". The Big Muff Pi was a cleaner (?) way of getting that distortion.
