Re: static humbukcer hum/buzz

UPDATE! it's not the neighbor or anything!
the way I play is :
guitar -> boss me-25 -> headphones. The boss output jack was most of the times connected to the amp, which I rarely use. So the amp was most of the time off. But lately I had it disconnected (since I didn't use the amp). Now I couldn't imagine there would be such a huge difference if I connect the output of the boss to the input of the amp. I connected it (with the amp switched off as usually) and the problem is gone.... What puzzles me is that the blazes still didn't buzz....

Re: static humbukcer hum/buzz

Hello, just a follow up, I have already odrered new push/pull pots, wires, to try the components on the buzzing strat first before re-doing the wiring on the Carvin. But today I saw that neither of the guitars had any buzz at all, no matter the orientation, position, AC or lightts.

Maybe a neighbor has a ham radio with a big a$$ linear ...

Re: static humbukcer hum/buzz

Check your Bridge grounding to the jack, if it's soldered to a pot, remove it and homerun it to the jack -makes a difference. Second check your wiring on your humbuckers and pot grounding -when you split humbuckers for paralleling or phasing it's easy to create a noise problem if you make a mistake or short something cramming it back together.. Lastly, shield your cavities with copper tape or Faraday paint and bring one ground to the jack from the shielding (once again NOT to one of the pot casings). These guitar techs busing grounds to a pot casing instead of homerunning them to the jack need to stop -or go back to basic electronics school. Homerun grounds ALWAYS to the jack -it improves the routing of external EMF to ground and reduces the overall signal to noise in the system.

Will keep it in mind. Makes perfect sense!

I heard copper shielding is better than aluminum.

Re: static humbukcer hum/buzz

^^^ Thanks, did some tests with aluminum foil yesterday and there is definitely an impact, the system reacts as I approach the foil. What's worse its my right hand that causes much of the noise. As it approaches (or even touches) the Super Dist the buzz goes more intense. I admit sometime, from a pro-shielding advocate I turned into "shielding does not matter", but now I believe that although shielding does not help in the coil-induced low-freq hum (60/50Hz), it greatly helps with mid/high frequencies.
So I will consider re-checking all bare metal grounding first, and second maybe re-do it from scratch in which case I'll definitely shield the cavity. (and the cavity cover).

I always used shielding paint until I did the Les Paul. I used copper tape for the LP in case I ever wanted to remove it. The paint always worked. So did the copper tape on the LP. But apparently aluminum works for a different source of noise than copper or paint (conductive graphite). At least according to Bill Lawrence. Here was his take on it ...

Like button seemed to have gone awry after whatever maintenance they did yesterday or day before.

Re: static humbukcer hum/buzz

btw my like button does not work with firefox 62?? I meant to hit like to the ppl above!

It seems to be an issue they know about. I’m sure the mods will contact the appropriate people to get it fixed.

Re: static humbukcer hum/buzz

I've had a bunch of pickups in a Les Paul ... Gibson Dirty Fingers and 57 Classics, Dimarzio, Manlius, Rio Grande, Seymour Duncan ... covered and uncovered. Every single one of them hum/buzzed. It originally had the circuit board and I pulled it and wired it the traditional way. It didn't make a difference, hum/buzzed either way. Typical situation ... touch the strings and the buzz went away or was greatly diminished. I finally gutted it, shielded with copper tape and it's silent with every pickup I've tried.
I have a Godin that hum/buzzed the same way. I shielded it with conductive graphite paint and it worked just as well. I have another Les Paul that I haven't touched, came from factory with Burstbuckers and it's quiet. Doesn't need shielding. Same with a Godin semi-hollow body that isn't shielded. It's quiet as well. I've never been able to figure out why some humbucker equipped guitars buzz/hum and others don't. I've had a few over the years that I shielded with the paint and others that didn't need it. An interesting thing is that I think every Asian import guitar that I currently own has black painted control cavities which I assume is shielding paint from the factory. They are all quiet as well (the ones with humbuckers).

There are members on the forum who will say that shielding doesn't work (on humbucker equipped guitars). That's not my experience at all but to each his/her own.

Re: static humbukcer hum/buzz

Both pups do this. the middle is SC so it groans and moans either way. But I cannot think that the Super Distortion is noisy while the Blazes absolutely silent.

Re: static humbukcer hum/buzz

I wish I knew the answer to this!
Pots are cheap enough to go ahead and swap out the components and see if that helps, I would think.
I’m not entirely convinced it’s the problem though.
I don’t recall if you said you had tried all of the offending pickups in that guitar? If all of the pickups have the issue in that guitar then yes, the problem is the guitar and not the pickups.
