A legendary fuzz pedal from Japanese pedal maker, Shin-Ei Electronics (新映電気). This added some minor tweaking on the stock circuit to adjust for my very personal demands.
1. Added voltage “Sag” VR 10K B to lower voltage down to approx. 3.5V
2. Added master volume VR 100K A
3. Replaced resistor values a bit to use parts in my pats drawer…
