Need Help! Ground hole location goin to Trem Claw on Warmoth Strat body

[Ardie]

:blob7: Hi Everyone!

Need Help! Can anyone tell where is Ground hole location entry point of the wire goin to Trem Claw on Warmoth Strat body?
Ive done copper shielding on the PICKUP cavity and the hole are nowhere to find..By the way is there a hole access at the first place?

I have search on this FORUM but i couldn't find anything related to this. I appreciate anyone can send me details regarding this issue..
cheers!

I don't know whether there is a standard location for the ground wire to pass from the pickup/control cavity to the trem spring cavity,but since both sides will be covered, either by the pickguard or your belly or the trem cavity cover, does it matter?  You could drill a small hole anywhere in the pickup cavity that is directly opposite the trem cavity and run the wire through.

Peace

You probably covered it up with the useless shielding you installed.

The only exposed body I have set up for a vibrato bridge has the pickguard installed already and I'm not going to take it off to check, but in the spring cavity the ground wire hole shows up on the bottom-rear side, almost exactly 2" from the rear wall of the trem route. I'd take a picture, but it's all black so I doubt you'd see what I'm talking about.

Thanks Bagman67.....

:sad: I have tested the wiring last night.. all pickups are working... But I noticed 1 thing.. i have this noise specially when I test it high gain..I install a Fender noiseless pickups.
I know its it normal to have that Hssss or hum sound when no been played.. but when i touch the input jack plate the sound eliminated.

:sign13: The only the wiring i didn't follow from the wiring instruction is the wired a Ground wire to Body cavity and Trem Claw.. Was this is the reason of the unwanted noise?

:blob7: Can anyone give me some tips... this is my first time trying to do the wiring...

thanks!

Thanks Cagey i will check it again... I will pierce thru from behind to find out the hole cheers!.....
Just curious I thought shielding is a good practice to minimize the interference...what is wrong in copper shielding?

Thanks

There's nothing wrong with it, per se. It's just ineffective. It seems like a good idea, which is why some people do it, but it's too permeable to have any effect. The hope is that it creates a Faraday cage, but there are necessarily just too many holes in it for it to work, and the EMI you're trying to guard against is of too low a frequency. The main culprits picking up noise are the pickups, and you're not shielding them at all. You have essentially about a mile-long wire acting as an antenna sitting right out in the open, so they're like a screen door on a submarine.

You'll notice that no OEMs do it, and they'd be the most strongly motivated to do so. But, they're pros, and they know better than to waste the cost of time and material.

The best way to get rid of noise is through common-mode rejection, which is how "humbuckers" and other noiseless pickup schemes work. That, coupled with individual shielding of conductors produce the least noisy guitars.

On the plus side, the heroic measures some guys to to with the copper foil in the control and pickup cavities looks really good in build pictures <grin>

And yes the extra noise you are hearing is from the fact that you didn't ground to the trem.

:blob7: Thanks Cagey

I manage to find the access ground hole from the Trem claw side, I also manage to add the ground for the Trem claw.... Thanks alot for the explanation

thanks alot guys!

Cheers!

I'm glad that worked out for you. Next time, you'll know to look ahead of what you're doing <grin>
