Shielded Wire Vs. Shielded Cavities

so, tone experts, wich one do you prefer?, wich is better (cost effective, easier to do, lesser noise when high gain, etc...)?, is ground from bridge necesary?, and why?


i wanna know 'cuase i'm really tired of the obnoxious hum that comes when my hands aren't touching the strings.
 
Re: Shielded Wire Vs. Shielded Cavities

Both is best? I would think both.

I used this stuff on my 31 fret build and i cant fault it, It hasn't got singles though haha The product itself is far better than other graphite/thinner base paint i have used. I would recommend it to anyone/

Ground from the bridge is required.
Shielding the cavity helps.
Twisting positive and ground wires on long segments also works as a shield.
 
Re: Shielded Wire Vs. Shielded Cavities

i'd say shielding is overrated. Too much trouble for negligible gain. If a pup hums, it will find its way to hum again, even if everything is shielded. If a pup does not hum, you will have to try hard to make it do so. Wiring also introduces hum, but not as much as a noisy pup.
My Aria Strat is not shielded and the wires are nothing special. Loaded with DMZ fasttrack 1/2 and the chopper it hums only when i want it to (not touch the strings)

I find running a earth to the shielded cavity helps too.

greekdude, I dont think the chopper and a fast track are a fair test as they are both single sized hums. True singles hum like a beast it becomes almost necessary to shield the cavity/

It sounds like neither option will help you, I think your guitar isn't grounded at all and thats causing you problems. Thats why when you touch the strings you become the earth and it quiets down. Get that earth grounded to the bridge and see what its like after that, chances are it will be good enough that it wont bother you.
 
Re: Shielded Wire Vs. Shielded Cavities

True singles will hum even with shielding.....its part of their DNA. Its interference from lighting or dirty power that shielding will help remove.

for example my shadow s100 with a bkp sinner in the neck hums like nothing else. Powerful pickup coupled with a big tube amp =humdinger
 
Re: Shielded Wire Vs. Shielded Cavities

Bridge ground is not really required if the guitar is well-shielded, but a completely shielded guitar changes the tone for the worse, IMO.

I've had box stock EMG's that were as quiet as a church mouse. No cavity shielding whatsoever.
 
Re: Shielded Wire Vs. Shielded Cavities

^ plus active EMG's have no effect when grounded on the bridge. Absolutely no effect. At the same time, EMG81 is not the most quiet active humbucker out there.
 
Re: Shielded Wire Vs. Shielded Cavities

Its not like EMG's are super special pickup technology - there are examples of dissected EMG pickups on the net. As I understand SD actives use similar technology.
 
Re: Shielded Wire Vs. Shielded Cavities

well, so both are good, and ground from bridge is not required, so the next question is, how to properly shield a guitar?

kramersteen, my guitar only had aluminum in the pickguard and a wire from the bridge to the ground in the volume pot.

PD. conductive paint is expensive as hell on my country, so no paint.

man, you got it wrong. Bridge grounding (in 99.99% of the cases) is needed. If you are ultra preventive, what you must take care is do the proper grounding in order to avoid electric hazard, coming from your amp. This might sound like pranoia, no high-end model that i know of has this, but there is literature out there, about using a capacitor which would potentially protect your body in case of electric shock. Drop me a line if you wanna go to this direction.
Conductive paint sucks. Best thing is self adhesive double side conductive copper. Next and equally effective is aluminum tape with similar characteristics.
 
Re: Shielded Wire Vs. Shielded Cavities

My original source for shielding was here : http://guitarnuts.com/ happy reading!, but do not take this as smth that will entirely get rid of hum. As we said, the benefits will be minimal. Your single coil will never be quiet as a humbucker.
 
Re: Shielded Wire Vs. Shielded Cavities

I have tried shielding the cavity on a few occasions, couldn't tell any real benefits to it... Don't worry about it anymore.

Try an ISP Decimator.... its a hiss sucking machine!
 
I use the copper tape on all the cavities, and solder wires running from each cavity to the ground lug on the Jack. There isn't a need to ground the bridge if you shield all of the cavities and link them together. If you want your guitar to be quiet when you let go of the strings, shield the cavities.

Yeah but does any of you pointies have true single coils?
 
No matter what you do, you can't stop single coil pickups from humming. But shielding gets rid of a lot of extra noise. IMO, shielding is very much worth the time and money. You will know what I mean if you ever play anywhere close to fluorescent lights.

There's a few solutions that work to varying degrees - but you are canceling the hum rancher than shielding from it.

Could be a simple dummy coil or one of the systems from Ilitch or Suhr. Didn't say it was cheap.
 
Re: Shielded Wire Vs. Shielded Cavities

the thing that drives me nuts isn't hum from the pickup (the guitar i want to shield is my V with the dimebucker, it's quiet when my hands touch the strings, but i want the axe to be perfect), but noise from the controls!!!, i think i should say that at the start...
