Overcast Fuzz

Just built it today and had some questions. There is a bias pot and I wondered if biasing needs to be done or is it for something else? It works but seems to be just another distortion/fuzz pedal. I need some more time with it before I decide if its worth boxing. Also, what are the chances the 3903 transistors are the issue? Are there fakes out there?
Thanks
 
No trimmer just a bias pot. But the closer to max the better it sounded. I obviously did not spend a lot of time with it but I could not dial in the sound I expected for Spirit in the Sky. As mentioned, it sounded like a generic distortion box.
 
Haven't built it but I suspect you'd need to roll back the guitar vol and likely go in unbuffered. Then roll back bias to get the broken, sputter.
Did you check gains on the transistors?
It's a bosstone, and it's sounds like it sounds like a bosstone.
Maybe check the demos for what settings were used to coax out the friendly Jesus.

Great ideas. Thanks. The HFEs are about 135
