Ritual fuzz no output signal

Hey everybody, inaugural post here.

I'm doing my rite of passage fuzz build and it was going well until I got to the trouble shooting phase.

I get good bypass sound but when the effect is on I get no signal coming through the clean channel on my amp and maybe a little barely distorted signal coming through on the dirty channel. That last bit was after I flipped pins 1+3 on the pot but I also try it on the dirty channel before.

A little diagnostic history;
First I thought there was a solder bridge on the strip board between the input and ground rail. Turns out it was because the input and ground wires were connected by the foot switch. Only found that out after I desoldered the input wire from the board. Far as that goes I'm stuck in a bad way.

Pictures are below aswell as the PCB diagrams and the off board diagram I got going on.
If you need better pics or more info let me know.

Thanks

Here's some general advice for stripboard builds. For the record I know those layouts work as I have build an iteration of them. Does the LED light up when engaged?
  • Confirm the layout is correct. Make sure your jumpers and cuts are complete. I've been guilty of not completing a cut on stripboard, but a drill bit can fix that in a few seconds.
  • Confirm the pinouts of your BJTs are correct and match the layout
  • Confirm all resistors/capacitors are correct values.
  • Double check there are no solder bridges. Run your iron in between the tracks a few times
