Hello Hello--
 I am working on the 60's Fuzz at your AMZ site and was wondering what resistor values need to be changed in order to "optimize" the circuit when using 2N3906 trannys [I changed it to PNP 'cuz the only germanium trannys I have for Q2 are PNP].  I hardwired the 2N3906's [Q1 and Q3] but socketed Q2 [germ] so that I could try different ones.
Thanks for any input!
Brian.

There's all kinda transistor's in FF's there with bias voltages to shoot for for different types of Q's.
 A bias pot on Q2 markedly quickens the biasing for Q swap interviews.

It seems that its a 3 transisor FF type thing?
 The last Q [in a FF] is the first one to get the bias pot on.
 So I guess where you'd want that would be Q3's collector.
