Hi Boris,
Your layout might work, but I dont understand how you wire the "SW2", because it controlled the "end of Circuit 2" and the "end of circuit 1, before the output section".
I've too search the "TL002" transformer but I don't find one everywhere ? WTF !!!
So where have you (Whitekeyhole) find your transformer ? What is the value for the Primary and the Secondary source because I don't find the datasheet on the net

...
So, for helping we a little more can you take a photo of your wired for the switc, because your explainations are not so light for me.
I'll post my perfboard layout I'm making for this pedal (make a pcb is very expensive ... ) next days.
Thank you Boris and Whitekeyhole for the help for this amazing pedal.
Guillaume ( scuse me a lot for my shitty english
