grounding trouble

[swal]

I am building a Son of Screamer, everything is done and it works. Except it is making lots of buzzing noise, but when I touch the ground on the output plug, or the conection on my volume pot  that goes to ground the buzz stops. :?   I resolder all my grounds and replaced all my wires and it still didnt stop the buzz. Any help would be great thnx.

try another guitar that you know has quite P/U's, you may have a grounding problem with your guitar or, a bad cord, your pedal may be having a problem with it's power supply, Filtering ! if you just built this recheck your circuit step by step to see if YOU wired it correctly and check each value as you go to make sure a incorrect value might be causing your hum,

guitars ok amps ok cords ok values ok power supply ok I just have to double check the wiring to the tone pot. could that be the problem? It is just really wierd that if i touch the ground all the extra noise goes away a pedal works perfectly, would putting it in a metal enclouser solve the problem?

That just sounds like a bad ground connection somewhere.

Is your amp well grounded?

yes it is grounded ok it is a 1 week old 100 watt marshall. All my equipment is working perferctly i just built arons boost pedal and it works perfectly no buzz nothing.  I am using the same battery clip and battery and the all the same equipment.

The buzz goes away because you are becoming a ground for the circuit.
The fix might be as simple as putting the circuit in a metal enclosure. Although, I have yet to have any circuit that I have built give me that sort of problem before it is placed into an enclosure. Are you absolutely sure that you have all grounds connected? Something just doesn't sound right...
How is your circuit constructed? Perfboard? There have been times when I thought I had everything worked out, only to find that I missed one little connection...

I took apart all the wires and rechecked everthing. the ground sleeve on my output jack of the pedal had broken and was completely seprate from the rest of the jack. and the 100k pot i was using was a 500k when i measured it with a dmm and it said 100k on the pot and pkging.  Two brand new parts thank u radio shack! No more buying from radio shack for me. thnks for the help guys

And the winner is... grounding problem! Mismarked pot, huh? I have been hearing that more and more these days. I think I might start checking those with my DMM from now on.

Glad to hear that you got it fixed.
