Kay F-1 Fuzz Tone w. mods
Modified Kay Fuzz Tone adopted for regular stompbox use. Mid and Treble controls is added along with a gain/bass boost switch. Also added a recovery stage since originals barely reach unity level.

Schaller Fuzz Sustain
An old fuzztone from West Germany which was housed in a wah shell. The treadle controlled the amount of fuzz and clean signal through a dual gang pot. There was an internal 22k trimmer which controlled the amount of gain.
Built it stock which works fine but it needed some improvements like higher output level and the internal trimpot was changed to an external gain control. Increased the value to 100k for more gain. Stock units had BC413C and BC239C transistors which is fairly high gain general purpose silicon transistors so BC549C's and 2N5088's should work equally good.

Top Gear Fuzz
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.
