Grounding / hum issue that is driving me crazy... little help?

Ok, for starters, long time lurker and first time poster. I joined the forum to try and sort out a P-Rails issue I was having but I ended up saying a lot of swear words and just ordering the triple shot rings for them. I tried my best but it wasn't happening.

Ok so, I have this guitar, a jackson warrior JS32T, it's a cheaper guitar and I got it from a buddy for peanuts for the purpose of making it into a metal machine. One pickup, one volume pot, simple and brutal. I should note I am semi-inexperienced with wiring as I only started doing my own wiring a few months ago. In that time I have done some really nice jobs if I may say so and I have done a lot of fairly complex set ups. So screwing up a 1 HUM, 1 VOL set up is driving me nuts.

What's happening:

hum and buzz when I have no hands on the guitar, if I turn down the volume all the way, it's gone and when I touch the volume pot, bridge post or jack, the buzz lessens almost entirely. The second I remove my hand from anything, poof it's right back. The solder joints are all fine, the ground is done in the cavity for the bridge post as with any TOM style bridge.

The pickup is a Seymour Pegasus bridge. This same pickup worked just fine in my les paul and not only that but every guitar I own is very quiet in front of the computer screen except this one and even when I turn away from the screen trying to find a silent or quiet spot, I end up with the same result. HUMMMM/BUZZZZZ

I am very new to the multimeter but when I tested continuity between the back of the pot and the bridge pin, it said it was fine. Currently there's no strings on the guitar but even when it had strings, I was the same thing.

Can someone give me a hand?

The symptoms definitely suggest a loss of ground to the bridge. When you checked it with the meter, you measured between the back of the vol pot to the bridge (or to the strings)? And the meter said 0.00 ohms?

I'd check it again, and check that your meter is set to the "ohms" setting and not to the "k ohms" or higher settings.

Definitely check out your bridge ground. The above post is spot on.

May have to sand down a spot on your bridge post to make a good connection.
