Retrograde Oscillation Help?

[pryde]

Just built up a Retrograde circuit (newest madbean pcb) and it sounds great overall BUT in the last 1/4 of the fuzz pot it goes into oscillation/squealing (uh-oh I am having a Boneyard flashback  ).  All values checked ok, no solder bridges, again it sounds and works great except the last 1/4 of fuzz.

I was wondering if anyone had this issue and found a fix? All parts were stock from the build doc with no substitutions.

Also, maybe someone cound post transistor voltages so I can make sure I am good there?

Thanks for your help in advance

I got the same problem.

I breadboarded the circuit .....no difference at all ! Same issue...

Anyone have an idea ??
