Who is on your Mount Rushmore of Fuzz?

You get four.

Four people who you believe have helped to define fuzz in music, and utilize it to demonstrate its musical potential.

These are the people that if a fellow musician/gear nerd was getting into fuzz as an effect and were asking you who are the best examples of musicians that best utilized fuzz, these are the people you would recommend to check out in terms of how they utilized the effect regardless of who they were as musicians.
