SOLVED Germanium fuzz not working

[Johnnyorange500]

Hi,



I’m having a bit of trouble with my Germanium fuzz face build. I seem to think I’ve soldered every wire correctly but I’m not getting any fuzz through the pedal. There’s just a dry guitar signal coming through the bypass and it also switches it off too. So I’m guessing the foot switch and input and output jacks are fine. I’ve just bought a new 9v battery too. All the capacitors and transistors are giving off an electric reading so they haven't burned out. I’m completely baffled as to why it’s not working. Would be very great full for some advice.

What are your voltages? and post pictures of your board and bypass wiring, including the switch and jacks.

Ok, no worries will do. Excuse the smaller tone pot it’s still the same value 1k linear. I’m no expert, so also excuse anything that might not be up to standards.

Managed it

It keeps saying my photos are too large for the server???

Try sending them to yourself in your messaging app. That should compress them, then copy them from there and upload those. That works pretty well for me.

We need voltages too.

We need voltages too.

Hi, sorry you mean test the board with a multimeter? For voltage?

Hi, sorry you mean test the board with a multimeter? For voltage?

Yes. Emitter, Base and Collector voltages for each transistor.

 

[Johnnyorange500]

Sorry can you help me with the right symbol to select on my multimeter for each of the different voltages I need. Thanks

Sorry I understand now I need to take a reading of each leg but what setting 2000 oms???

On voltage, DC current, not AC.

Sorry guys I’m pretty new to using this so if you could point me in the right direction to what selection to use.

Well we can't be both wrong

BTW I'm surprised that no one asked for the solder side of the perf board... Unless it's there and I missed it.

Bugger!! There’s no reading!!! It’s just staying at 0.00

Is the circuit powered? Do you have the leads connected appropriately? Touch one probe to one of the screws on the board and the other to the part you're trying to measure.

 

[EGRENIER]

BTW, I'm looking at the pictures and it looks like you sent the red wire to the pot ? and black to the board. I would suspect that to be reverse polarity. You red should be the + and go to you board.. no ?

I don't see any protection diode in there, but if you have one and my theory of reverse polarity is right, that would explain the 0V reading.
