i recently started a discussion on a humming noise when i put a volume pot in with a piezo.i tried putting extra ground wires everywere and it will not go away.the volume knob works more like an on-off switch.it will not hum when its completely turned down or when it is turn all the way up.but anywere in between it adjusts the volume but has a hum.help,i already suck at electronics and this is driving me crazy!

Hello , Its possible you overheated the pot when you soldered the ground on the back. Remember to tin the ends of the wire. Then put a small spot on the back of the pot, this should only take about 2 seconds of contact with your solder gun. Then solder the tined wire to the blob on the pot. Good Luck.
I'm not good at wiring either, but one of my piezo bare wires(the center wire) was touching the metal of the edge of the piezo and caused problems- hope this helps.
-Did you put a piece of metal where the strings go thru the body and run a ground wire to that?
-Did you try it without the pot and see if it still hums?
Do you have a multi meter to test continuity with? If you do, plant one of the connectors on one of your ground joints, and move the other to every other possible ground point -- including the tip on the instrument cable -- and see if they're all connection.
I'm not sure how that would be accomplished without a multi meter, though...

Do these and let us know.
