Twin Face volume difference from PNP to NPN

[JetFixxxer]

Both set to 4.5v.

NPN a lot noisier than PNP You can hear in this clip. First portion is just straight up guitar and then I have NPN and then PNP.

could be normal. this is the only effect board I have seen that combines the two and lets you directly compare the output.

probably difficult to tweak since the effects share a lot of the circuitry. others may have some ideas.

have you tried swapping the two NPN transistors on your board? easy enough to do if they are socketed, and it might make a difference.

I tried the other two NPN I have on hand as well. I might order a few more when I place another order..

Check the bias pot, but npn is usually a little bit noisier and the gain is higher as well imho.

Actually you can tweak the component values for each side, no problem.

There are basically two independent fuzz circuits, the only common components between the two are the Volume/Fuzz pots and the input cap.
