fuzz face with hum noise.

[boas]

Hello.
As I have been given good advise on this site before, I try again with another issue: I have just finished my first fuzz face, with two BC213 transistors. It has a really nice tone, but there is a lot of hum noise. I have checked the ground connections and they seem ok. Have anyone had the same experince, or have a good idea how to reduce the noise?
Thank you in advance for any answers.

The high gain of fuzz circuits means that any small hum on the input will be magnified alarmingly.
Try shorting out the input with a 100K resistor & see if it still hums.
If it does, the hum is coming from inside the circuit.
Are you using a battery? If it hums with input shorted & battery supply, then the hum is being picked up by the circuit from interference and shielding or at least shielded wire on the input and switching wiring is called for.
