I didn’t know how to build pedals. I don’t think I’d ever even used a fuzz. But I built this.
I had an old Boss BF-2 Flanger with a broken knob. I decided that as a distraction from rampant pandemic-induced guitar making, I’d try to fix it. The search for a 50kΩ reverse-log 12mm potentiometer led me to interact with the world of home pedal builders, and I got it in my head that I could probably make one.
The “One Knob Fuzz” from GuitarPCB seemed like a good place to start. It’s inspired by the Colorsound “Fuzz Box” from the 60s, and only has a few parts— mostly one transistor slamming into a another transistor until it bleeds. It’s filthy, chaotic, and you couldn’t turn down the fuzz if you wanted to. There are a few things that I’d do differently if I built it today, but it wails. The only annoying thing about it is that I wasted my best catch phrase on my first pedal.
This is the Coronacaster straight into the Aggressively Disinterested, hitting a clean Fender Deluxe. There is a brief example of the clean tone at the beginning.
