So I'm troubleshooting the Large Beaver (Russian) I've retraced my solder joints and cleaned up a few things but still not working. I can hear the pedal through the amp, everything works as it should...but just at an extremely low volume. Any suggestions? Any help is appreciated

Your soldering doesn't looks too bad, but it could use some improvement. I recommend going through and reflowing every solder joint, adding solder to the ones where you can still make out the shape of the eyelet. You should always use enough solder to fill the eyelets completely.

This process doesn't take very long and solves a majority of issues like yours. Clean your tip regularly as you go through it.

While you're touching things up, clip back any leads that are protruding. I see some on the switch, your jacks, and on the LED. These aren't causing your issue, but they can cause shorting.

You might want to check your resistor values. From your description it sounds like the signal may be bleeding off to ground. Pay close attention to any resistors that are connected to the signal at one end and ground at the other. If you had say a 4.7K or 47K where a 470K should be that could explain the loss of signal. If that doesn’t fix the problem I’d suggest making yourself a signal probe to help you track down where the problem is.

I went back and re-flowed all the solder points. Also just went through my checklist of resistors....Everything appears to be in their proper spots.

SOLVED IT!!!!!! Went back on found a cold solder joint on one of the grounds for the jack.


Holy smokes, what a relief....and what fuzz!

Great to hear! Enjoy the pedal, and post a photo in the “show off your completed build” section if you get a chance.

That has to be my favorite fuzz. Congratulations.
