Help defeat the hum

[BloodRose]

Working on a guit.. has Dimarzio Fast tracks in neck/mid and Duncan custom 8 in bridge. Volume knob, 3 on/off toggles
Bridge pup by itself has an annoying hum/buzz. Doesnt do so with any other pup on with it, and neither of the others hum on thier own.
What do I do?? Thanks

Custom 8, huh? Did it buzz before you did that mod?

Re: Help defeat the hum

I dont know. silly me did it before installation. But, I will disclaimer myself by saying ive dont about 10 magnet changes before with no issue.
Last time I had a duncan wired with a Dimarzio the duncan hummed and I had to reverse a wire.

First, you will need a weapon. Grab yourself a trusty sword...and stab deep into the heart of the dragon hum that doth live in your guitar.

Only then will you be a kinght of the round...guitar...table...thing.....

Check all your ground connections and ground wires. It's usually the little mistakes that drive one ape sh!t. :burnout:

Check the insulation on all the coil exit wires, perhaps during the magnet swap, some tape or heat shrink came free and you're now touching ground internally making it a single coil. Next check to make sure the shielding wire didn't break free from the humbucker chassis. Maybe the chassis isn't ground, but when you turn one of the Dimarzios on, they ground it via contact of some kind (like shielding paint, tape across a pickguard, etc-I don't know how the guitar is constructed)

It's got nothing to do with the fact that you're combining Duncans with Dimarzio. The wire swap you're talking about was probably to correct for out of phase.

Yeah, out of phase.. Ill tear into it and see. I can still hear the diff when I tap the coil so, I have it in bucker mode.

Thanks

What he said. The most likely culprit would be that the bare shield wire (assuming it's 4-conductor) was knocked loose from its solder joint with the baseplate by the magnet swap.

Re: Help defeat the hum

Yeah!! Got it figured out!! For some odd reason it wouldnt ground right when I grounded the same place it was stock. I opened up the sheath alil more and ran the ground wires all the way over to the back of the pot.
Sounds KILLER!! :arms:

For those that thought I screwed it up changing the mag.....:bsflag: LOL
