Just finished up my Weener Wah. It fired up the first time and all was good with the world. I decided to adjust the felt pads and went to fire it up and tweek the peak trim and I only have bypass and led when engaged.
I hadn't opened up the pedal at all from one test to the other ???
Need some help as to where to start on this. I'll be building up an audio probe tomorrow (should have done that a long time ago) but I have pics and Q voltages right now.

Q2 BC549C
C: 7.92
B: 5.20

Make sure your 3565 is making proper contact with the socket -- solder it in if you have to. Moving or jostling the pedal around could easily cause that and you should have some voltage on the base.

Ding!
I soldered Q1 into the socket and reflowed the socket joints on the pcb along with all the other solder connections while I had it out and bingo... Wah city now :D
You da man :D
