Germanium Fuzz Machine
The designed effect is modeled on the classic Fuzz Face. I used SFT322 germanium transistors (NOS). They have lower gain than AC128/2N404, which gives us a much lower level of distortion. Perfect for rock 'n' roll songs.
The Fuzz has a 125B style housing, "crocodile skin" paint coating, anodized aluminum faceplate, and laser engraved inscriptions.

Yes, only high quality.

Instead of the standard linear FUZZ adjustment potentiometer, I used the Rev-Log potentiometer. We can adjust the gain more smoothly. Each transistor can have an adjustable BIAS, allowing for accurate calibration.

How do you like it ?

I like it. Lots of nice touches. And I'm always happy to see reverse log pots in Fuzz Face-type builds.

A few questions/comments:

1. The knobs are awesome; would you be willing to share what they are and where you sourced them?
2. The faceplate looks great. Did you do it yourself?
3. I like the PCB layouts. Are you getting them fabricated at JLCPCB?Next time consider checking the "Remove Mark" checkbox when you're ordering, and they won't add the order number lettering.
4. Have you considered using ground planes for your PCB's ground connections?

Nice work, this is an inspiring build.

Thank you and I'm glad you like my work!

1. Knobs are not a secret. I bought them here:

Gałka wskaźnikowa KN24 czarna

Gałka wskaźnikowa KN24 czarna - Pozostałe - Wskaźnikowe - Gałki

amptone.pl

Price is ~$1/piece
It's a Polish store

2. I made the panel with a laser engraver, I don't have such technology at home.
Cost: ~$10/piece

3. Next time I won't forget about these numbers on the PCB. You're right, it looks ugly

4. I want to modify the ground connection with the housing, now I use grounding through the JACK socket.

Thank you for your comment!
