Fuzz face distortion pedal effects

Video showing a home-made fuzzface distortion pedal effect. The PCB was deliberately made as small as possible so that the final circuit could be embedded inside the guitar, behind the scratchplate. At about 0:45 the video pauses while a second pedal is replaced. This second pedal uses the same circuit but different transistors and capacitor/resistor values to create a different tone. The first pedal is based on the older, original "fuzzy overdrive" circuit. The second uses components often seen in louder, fuzzier "distortion" effects.
