O.K. so I'm new here, don't laugh if my problem seems a little obvious.
I installed a humbucker into a strat body which has the sheilding paint in the cavity, and grounded all the correct wires to the back of the pot (I used the vintage pushback type wire by the way) and everything works, but when I touch the strings I get a squeal.
Is this a bad ground problem or does my pickgaurd need to be sheilded?

Greetings and welcome to the board.
I would suggest shielding the pickguard, if you haven't already.
This may not be your problem, but shielding the cavity without shielding the pickguard is a lot like putting screen doors on a submarine... I prefer copper foil, but others will suggest aluminum for the cost savings. As far as one being superior to another for a pickgaurd, it doesn't make much difference. The advantage to copper is that you can solder to it.
Just a side question, but have you run a ground for the bridge?
Others will be by soon with more questions and suggestions.
Happy Trails

Why, no one can see thru the pick guard? Is this sound coming from you or the amp?  It could be a no ground problem. Is the bridge (and hence the strings) still electrically connected to the cable shield (usually thru connection to the back of the pots)? |

I ran a ground from the claw where the trem springs attach to the back of the volume pot. I wondered if the vintage pushback wire wasn't hardcore enough of a ground?

The wire is not likely to be a problem, but the solder joints may be. You can check the trem/bridge ground wire for continuity between the trem claw and the pot if you have a meter.

Hey there smfc1, welcome, think we can help-
Sounds like another signal ground terminal on the pot still connected via a tab or wire, The signal return (ground) should not touch the shield ground except @ the jack. Just cut the connection at that terminal, hear what happens. ;D
Which HB are you using?

Sounds like it might be a George Lynch Screamin' Demon. |

sf, Hi, and  to the NutzHouse! Feel free to SMITE the kylehead above, the one named "kylehead".... named that for the most obvious of reasons. A squeal, you say? Hmmmm..... Are you certain that your cord (or cable, if you prefer) is absolutely good? Is there perchance a hi-gain boost in the signal path? If not, then are you located in a high electrical acitivity area, like an industrial zone? Near a radio station of any kind, commercial or amateur? Even a CB'er? A large wireless network in the next building might also be suspect...... Lacking that, I'd say that you've reversed the wires to the guitar's output jack - when you touch the strings, you are connecting yourself into the signal path, and even without a lot of gain (from a stompbox or from the amplifier itself), you could still be making the noise. Stranger things have been known to happen.  HTH sumgai |
