Stockade bypass sound.

[Quentin]

I’m having an issue with a stockade pedal I recently finished. I get bypass sound but not when any of the foot switches are engaged. Any ideas or help would be much appreciated.

Is it possible that your jacks are wired wrong... i.e. sleeve to input and tip to ground ? I can't see them clearly but looks like it.

i swapped them around and now I’m getting sound but it’s really fuzzy sounding. Any ideas?

I could tell in the pic your jacks were wired incorrectly.. Id say get some 99% isopropyl alcohol and give both sides of the board a good clean to get all the flux off. double check your ceramic cap values and your resistor values..... Your transistors could also be very loose in those sockets causing an issue.

I did find Q1 and Q4 had the wrong transistors in place. I had used MPSA13 instead of the MPSA18. I still have no sound on the pedal. I get bypass audio just fine and I get a boost signal when I activate the boost foot switch.
??????????
I’m kinda stumped.

Well I’ve tested my transistors and went back over the circuit and still have no sound? What would be good voltages to check for?

Do you have an audio probe? If not, it is definitely worthwhile to make one!

There are a couple ways to go about this, one is outlined in this tutorial: https://forum.pedalpcb.com/threads/troubleshooting-101.9028/

The other is if you have a test platform like the Auditorium, you can connect a 100nf cap to the end of your "out" lead from the test platform board and using the other leg of the capacitor, follow the circuit along the schematic touching each point to see where the audio is cutting out.

Good luck!
