I don't have many fuzz pedals, but the Land of the Rising Fuzzz to me captures 60's fuzz. It's based on the shin-ei companion with a couple extras for you to tweak around with. I dialed in the guitar tone to the intro on the MC5 version of "I can only give you everything" effortlessly. I can't say it's the most versatile pedal, but it nails that agitated electricity sound that screams 60's to me. I love my Black Russian Muff but that's for meatier tasks.
