SOLVED Dream Fuzz hum/squeal

[Quentin]

Hello,
I’m having an issue with a Dream Fuzz I just finished building. I have bypass signal when the pedal is not engaged but when the pedal is on I don’t have audio and im getting a loud squeal. I’ve tired the controls all the way down or off and im still getting a squeal. The controls seems to change its pitch. Any ideas or suggestions?
Thank you all.

Double check your values and let’s see the rest of the off board connections. Maybe something’s screwy with them?

Looks like towards the lower right you’ve got a capacitor marked 473 in a spot marked 4n7. I think 4.7nf would be a 472 code.

That 4n7 cap was the problem. I double checked my other values and everything else was correct.
Thanks for the help eagle eyes.
