Fuzz Factory – OSH Park

Just soldered the first of three Fuzz Factory PCBs from OSH Park. Fired up on the first try. The board didn’t come with documentation, I had reverse engineer the board against the schematic to verify part numbers. Here is the schematic I used:

fuzz-factory

I used some AC128 transistors for Q2 and 3. The random choices from the lot sounded alright. I built this first board with sockets for the transistors for testing. I can test transistors on this board, if they sound good I can solder them into the other boards.

I like this board, the layout has pads for 16mm or 9mm pots. The width fits the narrow dimension of a 1590B box, which gives you the option to arrange the box in landscape like the original, or in portrait, like most standard stomp boxes. The Stab and Volume pots are mounted off board. While this adds some wiring, it saves cost by making the board smaller, OSH Park charges by the square inch, it also provides flexibility in how the box can be arranged. Hats off to the designer. Hats off to mr vex also.
