Help With Fuzz Face Circuit
I’m building a fuzz face circuit on my breadboard with two BC108 transistors. I have gone over this thing again and again and have checked all the components and they are fine yet I still get no signal out of it. Can anyone take a look at my work and tel me what I did wrong? I would really appreciate it. Thank you.

Hard to tell but the output cap (10n typically) doesn't seem to be connected to the 8k2. Again hard to see though. Any chance you could mark up the picture with the pot leg numbers. I think I know which is what but hard to say when we can't see them. Try and beep out continuity between all of your connections with a digital multi meter... Maybe the breadboard has seen better days? Those things drive me mad.... Lol

Why waste your time with these notoriously unreliable breadboards? It's certainly quicker and easier to just solder the circuit together on a piece of stripboard, especially as the Fuzz Face circuit uses just two transistors, four resistors, three capacitors and two pots.
Word of advice - you'll find that the silicon Fuzz Face like you're trying to build has a huge amount of high frequency "fizzy" content in its output. You can tame that by adding small value capacitors (220p - 1n - select to taste) from base to collector of each transistor.
