What do you get when a One Knob Fuzz collides with a Big Muff Pi Tone Stack? Ok, minds out of the gutter...The Big
Knob of course! I've always felt the One Knob Fuzz could use a tone control for versatility as well as experimentation.
The Big Muff Pi won the deal, it marries seamlessly with the One Knob Fuzzes expressive output. 16mm pot spacing and
silicon transistors make this project a good contender for a silicon fuzz with "bang for buck".

- Page 1 Big Knob What do you get when a One Knob Fuzz collides with a Big Muff Pi Tone Stack? Ok, minds out of the gutter…The Big Knob of course! I’ve always felt the One Knob Fuzz could use a tone control for versatility as well as experimentation.
- Page 2 Note that you will need NPN germanium transistors (PNP’s will not work). I have tried low gain NPN’s (60 and 80 hfe) and they sound very good. See the sound demo of the Big Knob for an example.
- Page 3 Shopping List Although I do not stock all components you will need for the Big Knob, a lot of what you need can be found on my store. The remaining parts you will need are an enclosure (1590b), A 3pdt footswitch, led and current limit resistor and bezel, the 2 potentiometers and any other aesthetic additions you choose.
