My mom always had these cans lying around, and what did they have in them??? Cookies? You know damn well aint no cookies in there. My mom kept sewing supplies in them. She sent me a can that actually had cookies in it...and that diddnt sit right with me. I made the can into a Fuzz Face pedal. The pedal has controls for volume, fuzz and bias, and can be powered with a standard 9V center negative adapter.
