From the post
Jus Oborn of Electric Wizard has been seen using one of these so I had to build it. Raunchy fuzz but suffers from lack of output and the Boost control isn't a favorite of mine. So here is two layouts, one stock and the second with volume mod and a more useful Boost control. I also added a small pF cap across base and collector of Q1 to smooth things out a bit.
