Good day sirs,
So this is the story. I've just installed a new bridge pup, Dimarzio x2n, and it buzzes like hell and also it is out of phase in my neck stock pickups. So I reverse the X2n's wiring as instructed by dimarzio pickups in there website. But it got worse because when I touch the pickup selector or the x2n's body, it buzzes horribly. If I touch the bridge together with the x2n, the buzz goes away. I was determined to eliminate the buzz so I wired the x2n on the correct spot again which is red to hot and green and bare to ground, but it doesn't help, the buzz is horrible when I touch the x2n or the switch. What should I do next?

This suggests a poor connection to the ground side of the circuit or perhaps if your output jack was disconnected during your wiring, you might have reconnected it with the ground going to the tip and the hot going to the shield.
Also worth considering, perhaps your guitar cable has a poor connection on the ground (shield) side. That's easy enough to take out of the equation though. Just use a known good cable instead.
Good luck and Merry Christmas.

The amp and the cables are the first thing ive checked. I went to a music store and tried every amp and cables available but nothing helps, still buzz. I hired an electrcian to do the soldering for me. I think it was good as it gets. We checked for continuity and from my bridge, knobs and jack and it was good.
I noticed that the hum is horrible if I select the bridge pickup only and it gets much horrible when I touched it, but if I touch the rails or poles ( im using hot rails on my neck pup) of my neck pup the buzz goes away as well as if I touch the TOM bridge. If I select my neck pup and both pick up, the buzz lessens about 80%. And if I touch the neck pup after selected it, it does not buzz horribly like my bridge pup do, it lessens the noise.

That tells me the ground wires for the hot rails and bridge are properly connected. The earlier parts of the discussion lead me to believe the ground connections to the X2N and the switch are faulty. I re-read your initial post. Unfortunately I had overlooked the part where you mentioned the buzz going away when touching the bridge, on my first reading.

ravi, So, to recap: * The X2n buzzes when selected by itself, but sounds OoP when combined with the Neck pup; * Reversing Red and Green makes the problem worse; * Touching the bridge (effectively, the guitar's ground) and the X2n's metal shell quiets the buzzing. Is that about right? Sounds to me like the bare wire isn't connected to the pickup's metal shell. It's also possible that one of the connections inside of the pup might be touching the shell, particularly the joint between the two coils (which is usually taped to prevent this, but you never know....). My only question now would be, when you touch the shell and the bridge (effectively, the guitar's ground), does the pickup's signal get weaker, or is it just as strong as the Neck pickup? You can use a MultiMeter to check for continuity between the bare wire and the shell. If there is continuity,then touching the shell with your hand should not reduce the noise any further. At that point, I'd hazard a guess that there is an internal problem, and you might want to exercise your options vis-a-vis the pickup's warranty. (You did say it's a new pickup, I'm assuming that it hasn't been sitting on your work bench for a year or two.... ) HTH sumgai

UPDATE:
OK guys, i just swap my x2n to bill lawrence 500xl. The buzz was still there. The same problem as the x2n. If i touch the blusa 500xl or the pickup switch or selector .. it has a buzz like the x2n. I also swapped the stock pick up but it did not help either, same problem as the x2n or blusa 500xl.
Mr. Sumgai, The x2n baseplate is grounded properly. I unscrew the pickup to the body and touch the baseplate and i cancels out the buzz.
I concluded that it's not the pickup. It's the electronics of my guitar. Can toast potentiometers or switch can cause this buzz?
