Fuzz Face Schematic

What are some ways to troubleshoot a fuzz face guitar pedal?

I built a fuzz face guitar pedal earlier by scratch. I followed all directions, and have all pieces needed (ex. resistors, transistors, capacitors, etc.) but when put together, the sound doesn’t go through. It just comes out all crunchy and at half the volume it should. All potentiometers are set correctly, and everything is in place like my Schematics showed. What can I do to achieve a fuzz sound?

make sure the solder connections are good and that the pots aren’t grounding out to the case.
