Humm trouble in nugget fuzz

Hello,
i just completed a nugget fuzz and it gives a slightly gated,low battery,slightly sputtering fuzz sound.
The pedal is without humm this way.
When i turn the bias further clockwise the fuzz opens up and sounds fantastic but there it also introduces a horrible humm.
Is there something i can do about that humm?
Could there be something wrong with transistors 4 and/or 5?

thanks in advance,EdJ

I know it sounds a bit like,I ve bought a telecaster and now i want to sound it like a Les Paul but the sounds you get with the trimpot wider open are simply beautiful.I would be very glad if someone could tell me if the humm is normal or did i make a mistake and or used a bad component.Would,for instance,expirimenting with lower gain transistors mak sense?Thank you for your time!

That’s normal. Replace the trimpot with a regular potentiometer and mount it externally, now you have an NG3.

It will hum when you have the drive and bias pots above 12. That is normal for this circuit. Just find your setting.
