My LP Has Been Invaded by Those Noisy Gremlins (Solved!: Post #43)

Is your bridge ground intact? I had one break on my V and it was noisy no matter what I did.
AFAIK, it tests as grounded through my meter's continuity test and when I touch the bridge, tailpiece, and the strings.

What's also weird: If I hover my hand over or actually place it over the tone knobs and the output jack, a lot (not all) of the unwanted noise subsides. And all my other humbucker guitars are very quiet, too.

Tomorrow I'll start with replacing the tone pots and recheck the caps before I move on to the volume pots.

Pull your pots and line the bottom of your control cavity with copper tape.

I am inclined to try this as Robert says. If it were me and I really wanted to test for known good and eliminate the obvious until the culprit is located, I would shield paint and copper foil everything and re install the exact setup and see if it still makes the noise. Go No Go test. Then if still noisy, regroup and begin with ground wire testing, or

Have a totally known quiet set of pups, pots, caps, switch, jack and wires,,,,,,,,,,,,,,,Install that prior to any shielding and see if it makes same noises. Go No Go here too. Make sure no Dimmer switches are in use anywhere, change location of amp,

I have also heard of players who got unwanted noises off their rear control cavity cover. Like it had static. Some folks tried rubbing drier sheets on it, Static Guard and of course Foil Tape on inside of cover, IIRC

You will get it Greg

The only thing I touched at this point, was to reposition those caps from Modern wiring to Vintage wiring.


It also looks like the caps are different units. Pots and Ground wire and other items look different too.

Yes they are. I replaced the original pots and bumblebee caps with an a upgrade kit from RS Guitarworks about seven years ago. All was fine till about a year ago when I first noticed a minor increase in background noise.

As much fun as it sounds, I would be extremely hesitant to do any kind of shielding in an R9. Especially since the problem wasn't always present.
Exactly... :cheers:

Hence I posted this if no shielding.

One thing I know about Greg is he is far smarter than the level of knowledge needed to diagnose and fix an LP set of Pots, wires, pups, switch, jack and grounding system.
Ha ha... Obviously not smart enough!

Pot Day came and went... No difference... :BH::BH:

I wish I had extra humbuckers to try. Don't really want to borrow any from another guitar. Maybe this is a good time to buy and try something different. But I do like the 57 Classics too. And if new pups dont do the trick, I'm going to have an epic meltdown... :run:o_O:cry::dancepoo:

Now Now NOW,,,,,,,,,, U worked your magic on my TS9 and you made your own awesome AMP(S)?

Can u also do me a favor and try 2 or more Humbucker guitars in the amp that is where you hear this noise. I am also assuming NO Pedals are anywhere in the chain. Any measure of similar noise if diff guitars?

I only ask this because once I was chasing all manner of interference I thought was grounding on my Epi LP. Turns out after trying Solid state amps, Tube amps, cables, different guitars, I realized that because the issue happened sometimes with the LP and sometimes it behaved properly, I looked for other outside factors. Turns out that if I was home alone playing, no interference. But if family members were home, the ceiling light in the living room below me would be on. Naturally, that fixture operates via a dimmer switch. Turn light off, noise gone, light on, noise present.


Also, what are the chances one of the caps is leaking?

Yes, I've tried that. The noise follows that guitar only, and all my other guitars with humbuckers are pretty quiet. Yesterday my wife witnessed the difference. First the LP, and the wifey says: "Buzzy!". Then I plugged in one of my SG's: Wife now says: "Is the amp on?"

I did have extra caps to try just in case.
