Okay so I have my 2 new DiMarzio humbuckers in, PAF Pro in neck and PAF Joe in bridge. These pickups are on the outside of my single coil that came stock with my ibanez S470DX. My guitar is makeing a buzzing noise in clean and distortion, and on every pickup selection. It makes a crackle like noise when I move my guitar around. When I plug in my old washburn, its fine. Any suggestions guys??
Thanks,
-Joel

Sounds like you have a short somewhere, or something was wired wrong.

Or possibly earthing - if you touch a piece of wire from the metal body of the lead ( where it enters the guitar ) and touch it to any suspect component, IE the pick ups - and the humming stops - its not earthed

I've repaired Gibson and fenders and noticed this:

Gibsons with double coil pick ups have the unused spare terminal of the volume pots connected to the pot body -I believe this is to eliminate mains HUM

Whereas Fenders with single coil pick ups do not ( half the output )

Unfortunately I have'nt had the opportunity to open up an Ibanez

Please feel free to mail me privately - intrigued

Well guys it's not really a constant hum or buzz, its like a cracking when I move it around my body, but not when its in the air. My uncle says it sounds like static, and he opened it up and checked his wiring, and he says he did it all correct. He also checked the groundings, and tightened them up. It's very weird because it will crackle on all of the pickup selections, even though he didn't touch the single coil. It really blows my mind...

Hmm, fascinating, does it make any difference when you touch the strings ?
And has it got a sheet of metal foil on the reverse side of the scratch plate, as this is relied upon for grounding ?

The only other thing I can think of is that dimarzios have a selection of wires to use, and you might have wired the double coils in series instead of paralell.
I've never done this and do not know what effect it would have ?

I would disconnect one of the pick ups completely and experiment with just one of them - to see if you can lose the fault

If you have wired the double coils in series - the output would be considerably lower.
If you've wired them in paralell, you'll have twice the output of a single coil.
Blown my mind now - going to the Pub

Hmm when I get better with a solder gun ill check it out....until then im going to try the earthing theory that Gramo had. I'll let you guys know how it goes. I can't remember if I stated this or not, but when it crackles, it comes through the amp even on the clean channel, as well as the distortion channel.

Well Grambo I tried the wire trick, nothing worked. No, it dosen't stop when I touch the strings, but it isn't a constant crackling, only when its against my bod yand it moves, very weird. Uh how do I tell if it is series or parallel wireing? I will find out if it is there is a metal plate tonight in the back of my guitar.

[font=trebuchet ms]Check the contacts of the jack. I suspect that the jack is not making good connection to the cable plug.[/font]

YEAH, nice one - if it's on all pick up selections and both channels, it's something common.

Output jack socket - something loose - bent contacts ?

Well today I took the back plate off where the pickup selector is, and when I moved my guitar around there were no crackles at all. I look at the ground wire, and it was sticking up pretty far, and might have been touching the back plate. The plate has a very thin layer of foil on the side that faces the pickup selector. So I pushed the ground wire down farther into the cavity and put the plate on, and it hasn't crackled since. I'm going to check it out later and see if it does. I'll post back.
