On my Royal Precision pedal steel, I sometimes can feel a mild buzzing sensation. Also when I touch the neck it creates a buzzing ground hum type sound.

The pickup has 2 wires soldered to the output jack. Should there be a 3rd wire coming from the guitar bridge that should also be attached to the ground wire soldered to the output jack?

The outlet is a 3 pronged grounded jack and I've checked to make sure the outlet is grounded. This happens no matter what amp I'm plugged into. Thanks.

If the AC cord or plug on the amp have been replaced, make sure they are wired right...

shouldn't be a problem with the steel unless someone 'modified' it incorrectly.
seems to be alot of that going around.

Check *carefully* the grounding on that amp. It should not do that, and it's frankly unsafe until you get it fixed.

You don't wanna go like Keith Relf. Don't be the ground path.

Are you using any extension cords? We had an ex-band member make up some heavy-duty extension cords...wired one end backwards...ground was hot, hot was ground. We kept thinking it was certain places as we didn't always use that cord. Finally discovered it and rewired it.

The problem is in your amp. And it could HURT you.
Get it fixed.

I'm probably stating the obvious, but have you tried the steel into a different amp?

Have you checked the outlet with a ground tester? I have had similar things happen due to bad wiring in a house. It didnt bother anyone else in the band because their strings weren't grounded to the guitar/cables/amp.

Is this happening on a basement floor?

Are ALL components in the rig plugged into only one power strip? They should be.

Is the ground pin on the amp's AC plug intact?

Is the wall outlet truly grounded - 3 prong?

I've got 2 steels and 2 amps - Peavey session 400 and session 500. With the RP, no matter what amp I'm plugged into, when I touch the metal parts of the neck, it creates the hum. The other steel doesn't do this, regardles of the amp. Which is why I thought it may be the way the pickup is attached to the guitar. I think on electric guitars you have a wire from the bridge that ends up getting soldered to the ground part of the jack. There is no 3rd wire on the guitar, just the 2 wires from the pickup.

Part of the house does not have grounded outlets, and parts are. It looks like they made them add the grounded outlets in the kitchen, and thats where I plug into.
I make sure anything related to the steel gets into the same power strip and into the kitchen outlet. I have a ace hardware power strip, with a light that turns green if the outlet is grounded, and the light is green. It's a one story without a basement. Normally if there is a grounding issue when you touch the strings or metal on the guitar, it quiets a hum that you already hear, but in this case it creates the hum, when the guitar is quite. It's not a real jolt shock, but if I lean over and touch something, I can feel a mild tingling sensation. This has been going on for a few years now, and I'd to get it corrected. Thanks.

I'd get an outlet tester.
And run a jumper wire from endplate to the screws that hold the pillow blocks. If it's a D-10, to each neck.

Grounded outlets in a home doesn't mean they are actually grounded. I had to replace several 2 prong outlets where I am living to 3 prong as to not have to keep using adapters. But, I did not run a third wire and attach to a grounding rod. The outlet checker will tell you if there is a ground. I carry one in a briefcase bag that carries all my power strips, extension cords, mic, and some other stuff. As American Express says, "don't leave home without it".

If your two pickup wires are unshielded and not connected to a ground plate, try reversing the wires at the jack.

could be that the jack is isolated from the body of the steel and therefore not grounded.

Make sure its grounded to the metal frame of the guitar

Yessir. Read it loud and clear; also read "felt a mild buzzing sensation". That is bad and there is a bad A/C ground, and not touching anything else until it's fixed properly is the right way to go about that.
