I know this isn't a guitar support forum but I also know that there's some extremely knowledgeable guitarists around here who may have experienced this problem before.
Last night my wife bought me a Tele that I have been wanting for awhile. When I plugged it up to my amp I got a lot of electrical hum that would stop completely if I touched the strings, pots or switch plate. It does this on all the settings.
I don't think it's the amp since my Les Paul doesn't hum at all.
I don't know if this will help or not but the pickups are Texas Specials.
I've googled and it seems like my strings may not be grounded properly. Does this sound about right? Should I start by reflowing the solder that connects a ground wire to the bridge?

Yes, grounding.
Yes, the bridge to grounding wire has gone bad or something.

Okay, it's the grounding but not on my guitar. I took it to the guy who works on all my dad's instruments and it worked fine, no hum. It works at my parents' and my brother's houses too, no hum. So my dad's buddy says that it's probably some electrical outlets at my house that arent grounded properly and that the pickups are picking up the noise. He took it apart and checked all the connections and nothing was bad. The jack was okay too as are my instrument cables.
So, other than getting my house rewired, it looks like I need to get some Noiseless pickups or deal with the hum.
Does this sound right to everyone? Also, this is a little off-topic but would noise/EMI be responsible for my baby monitor being so static-ee?

Maybe you should start checking your amp's power chord. Or the specific outlet. Have you tried the amp in different rooms ?
Have you tried the same amp and guitar combination at your parents house ?

The amp's power chord had a little exposed, yet sheilded wire, where it meets the plug. I taped it.
I did try the amp in different rooms with no change.
I didn't take it to my parents' house so that will be the next thing I try. Thanks.
With my Les Paul working fine when paired with this amp could it still be the amp though? With a noise problem on the amp, could the humbuckers on the Les Paul do away with the noise while the single coils on the Tele hums?
Also, now that you mentioned the amp, the Tele doesn't hum when I have it on the dirty channel. Shouldn't it get worse when it's dirty if there's nothing wrong with the amp?

Yes, single coils will make a little more hum. Yes, grounding.
Yes, 60hz notch filter. Why not?

Well, now I'm getting the hum on the dirty channel also. Oh well. I'll try the amp at some other places if I leave my house today just to make sure.

One place in your house where electrical outlets should definitely be earthed is the Kitchen. Tried it in there?

I just put it in a kitchen outlet with the tester button and no hum on clean or dirty. I guess I'll install a CFGI outlet upstairs and see if that solves it.
Do I have to turn off the electricity at the breaker box when I do this?

You probably have a ground loop. Look it up on the Internet and they'll suggest ways of getting rid of it. This happened to me when I moved house. Relatively simple to eliminate though.

Yeah ground loop is probably what it is. I'll try to find a way to get rid of it. Everything I've found so far is a little expensive or dangerous. Troll, what did you do to get rid of yours?

Been inclined to wander... off the beaten track.
That's where there's thunder... and the wind shouts back.

Well, I managed to get rid of most of the hum just by rearranging the cables and plugging my amp into a different plug. But I then got one of those mulit-plugs that has a surge protector and a ground loop eliminator built in. Not cheap but it worked.
