This is a pumped up fuzz kit from pedal parts and kits. I built one of these a few months ago, and had great success. This one’s giving me a bit of fits. I have an external trim. The pot is a 10 KB pot wired pad two to terminal two and pad three to terminal three. It’s wired in series with a 3K resistor to terminal two. I’m getting a massive volume reduction when the effect is engaged. Let me know if you have any tips.
