These are some more PCBs from OSH Park. There is an IC Big Muff, Tube Steak, and a Woolly Mammoth.
The Tube Steak I created from a schematic posted by Charlie Barth at Moosapotamus.net. Tube Steak Fuzz is a cross between the Tube Sound Fuzz, and Way Huge Fat Sandwich. Here’s a link to Charlie’s article read it for yourself: Tube Steak Fuzz.
The IC Big Muff also called the op-amp Big Muff was a version of the Big Muff that used two op-amps in place of the four transistors used in the classic Big Muff Design. Here is a link to more information in the op-amp Big Muff.
The Woolly Mammoth is a PCB design that I made as a clone of the ZVex Woolly Mammoth. I really like the sound of this one. Designed as a fuzz for bass, it sounds good with guitar also. The design is based on the Fuzz Face.
