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!!

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.

thanks for the reply. Ive been using a 500 pot but no capacitor, ive always used tone capacitors on the tone.  should i be puting one on the volume?  I'd really appciate any more help you could offer

thanks

jim

 

 

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
