Hello again Boratto!
Damn, you're a fast learner, the layout looks really good considering the short time you've been doing this.
I'm really looking forward to see how this developes...
Here's a few things I found:
- remove trace cut between 10k and 150k resistors (middle of board, audiopath between q1&2), as it is now, your audiopath/signal stops after the 10k.
- insert trace cut directly underneath q2 (unless you got one underneath the 1uf cap) so that you don't get +9v into your audiopath.
The rest looks good to me.
Remember to socket JFets incase you should be as unfortunate as me and has gotten J201's that are off specs. I've hade some that would never bias correctly nomater what I did (coul not get the voltage at drain below 6-7v, even when increasing the size of the trimmer to 1meg)
