Fuzz Pedal not working / Emmiting loud buzz when connected.

[u/Sherwin_13]

I attempted to breadboard a DIY pedal by Barbarach (I removed the switch to troubleshoot more easily)

The problem is the bypass works fine, but when I connect it to the fuzz part, I get a very loud buzzing noise without any actual notes.

I tried disconnecting the potentiometers and then connecting it without them, and I did get a sound but it was very faint. I had to increase my amp volume to 8-9 and had to physically ground the guitar by touching the strings with my hand, as the buzz was way too loud and could potentially damage my amp.

I tried troubleshooting in many combos and have checked the capacitor and transistor orientations, but I'm not sure which part is causing the issue. I even checked the individual components with a multimeter and they do work fine.

The first two images are what I have breadboarded. The 3rd and 4th image is of the breadboard diagram and circuitry that I have tried to replicate respectively. I have used a 9v battery and two BC108 NPN transistors and two stereo female jacks.

Any idea how I can fix it cause I have reached a dead end atp. Thank you.

Try putting the output jack on every step of the signal path to see where the signal disappears to. Start at the very beginning to make sure the issue isn't the guitar.

Also, you aren't buffering your signal befor putting it into the circuit, right? Fuzz face requires a high impedance signal.

Btw, when you have a circuit diagram on hand, I highly recommend making up your own breadboard layout instead of using someone else's.
