my first post:
can anyone explain why this is so LOUD without any of the typical fuzzy/screaming/stuttering distortion?

j201
D 6.65V
S 0.316V
Vp 0.6V

j177
S 5.82V
G 6.65V
D 0.295V

thanks

It's supposed to be loud - it's a booster! You might want to put a volume control on the end.

It's not fuzzy because there aren't any clipping diodes, which would also limit the signal and make it less loud.
Bringing you yesterday's technology tomorrow.

In response to the questions in the forum - PCB Layout for Musical Effects is available from The Book Patch. Search "PCB Layout" and it ought to appear.

Pls note also: there's only ONE gain stage since the second stage is unity gain follower.

Whilst it looks like one, I don't think it is....it looks like a boost to me.
