Buzzing with volume pot but not when up full !!

Posted by Jim Junksville Sharkey on October 26, 2011 at 3:24pm

Hi guys, really hoping you can help me here.

I've looked but can't find an answer to my problem.

When I wire up a piezo to a volume pot I get a buzz whenever the volume is around half way up,around 4 to 5

but when I turn it up full to 10 the buzzing just disappears, you would of thought that any buzzzing

would get louder the more you turned the volume.

I've tried 3 pots and 3 pickups on 2 different amps, same problem with all them, checked and double check the wiring diagrams and all solder joints...HELP!! please it's driving me mad!!

    there a few thing if you a three post 1/4 in. plugin you could have wires connect wrong, or you could glue some tin foil on that connect your 1/4 plug and your volume pot. you may also either silcone your piezo or glue it between two thin pices of hard wood

    What size capacitor are you using? If you are not using one you might want to try a 500ohm in the circuit. I had tha problem once and it turned out to be a bad pot. It was either bad to begin with or I got it to hot when soldering.
