Slight modifications to my Tonebenderish fuzz. Put a pot in series with input. In minimum all input signal is fed to the first transistor. With high output pickups this can really drive the circuit in to deep saturation with some serious barf. At maximum it limits the current driving the first transistor. This cleans up the sound and gives a less fuzzy sound. Also dialing down the guitar volume a little bit cleans the "barf" nicely.
