your favorite fuzz

Give the Sprout over at MadBean a try. I'm in the process of modding the design a little bit, and I'm able to make it do some of the stuff the Fuzz Factory does, but without all of the oscillating.

I like this one.
An adjusted 2 transistor fuzz type circuit.
Make the 5K an external bias control.  Try 2n2222s and other Si transistors.  Adjust C3 and C1 values to taste.  Increase C4 value for more high end roll off decrease for less high end roll off.
1k is gain, 5K is bias gated to compressed, R11 output volume

I always liked the simple little Colorsound One-Knob Fuzz...I just finished building and testing "Earthscum's" bazzfuss variant..very nice!
Now, dad-rattit, I guess I'll have to try Gus' circuit!

  Gus's could be called 'modern' but 'thought through thoroughly' seems an appropriate tag for most/all of his circuit designs, the FF is not the 'prettiest' scheamatic, but legit and legible. I built that on a bookcover and put it in a mouser box with cardboard input and output jacks for starters, wayyyy back whennn...just after I finally got an RM working. Very smooth working FF circuit IME.
