A replica of the electric guitar effects pedal fuzz face

Special Notes:

1. Capacitor C4 is a non-polarized capacitor!!! (Drawing made a mistake, too lazy to correct it)
2. Replacing R1 can adjust the tone.
3. A design was created that allows for transistor replacement; female connectors can be attached to Q1 and Q2 to quickly change transistors and experience different tones.
4. Be careful not to plug it in backwards when connecting the electric guitar!!!
5. 500k is for volume adjustment, 1k is for distortion adjustment.
6. Since I'm not an experienced audiophile, all the transistors used are new.
7. I couldn't find a new 20uf capacitor, so I used a 22uf one instead.
8. There's no casing yet; I'll post it as soon as I finish it. You can DIY it yourself.
9. Uses a 9V battery.

 
Note: It's best to use low-power transistors. I've tried 3AX31A, B, and C. Use other transistors with caution. (
Below is the schematic:
The PCB is very simple, but it works.) (
