From the post
The Lunar Module was designed to get that Gilmore fuzz tone from Dark Side of the Moon. It's an aggressive silicon fuzz with a wide range of tones. Got a request for this with the Pregain control as a trim pot. As the original 3-knob Lunar Module had the Pregain and Brite controls as trimmers, making a board for both is fairly easy. Transistors are BC109Cs, but BC550Cs would also work. You might want to use linear pots for the Body and Fuzz controls as some builders have had better results with those than the stock tapers.
