Noisy Stratocaster H-H Installation:

I recently installed twin PAF's in my 1987 Squire Stratocaster. Of course, it was fully shielded with conductive adhesive copper tape. All sections of the cavities have 100% continuity. There is a ground wire soldered to one section on the copper tape, in addition to a tremolo/bridge ground and input jack ground. The back of the pickguard is covered in copper tape and the pots and switches run directly along one, uninterrupted piece of tape. There are "ears" of copper tape that fold over the edges of the cavities that come into contact. Even the adjustment springs and baseplate of the pickups are grounded because the springs contact the copper tape as well. The tremolo spring cover is backed with aluminum tape, as I ran out of copper.

I have a very persistent noise in this guitar, as if frying eggs. I was using GFS wax potted, nickel covered (8.6k Bridge - 8.0k Neck) PAF's initially, and then switched to Gibson 57 Classics, which are around 7.5k each. Guess what??? The GFS PAF's are MUCH QUIETER than the Gibson 57 Classics, but the noise is still ever present.

When I switch between positions, the noise remains constant. If I roll off the volume or the tone to about 1/2 way, the noise goes away. I'm running 500k Alpha pots on this rig at present...single master volume and single master tone.

The 5-way switch is one of the cheapo, plastic ones, identical to the one that came in my 1987 Squire. The switch is a little scratchy.....but I have a brand new 3-way Switchcraft (all metal) out of a recent Schechter build, so I can easily swap that in later.

My current practice room has no dimmers...in fact, we have no dimmers in the entire house. Both my Marshall DSL40C's are dead-quiet when switched on without the guitar plugged in. I have switched cables. There is no buzz or pop when any metal part of the guitar is touched. You can touch the pickups and the noise does not change. I am confident the problem is in the guitar itself.

Then, I made an interesting discovery...If I moved as far away from the amp as my 6 foot practice cable (Whirlwind Professional) would allow...and then turned a certain way in the room, the noise diminished, almost totally disappearing!!! And that was with no lights on and no electronic devices in the room.

What's interesting is, my EMG equipped Schechter does not behave this way, so it's only affecting my "passive" guitars.

Very interesting...Thoughts????

all that damn copper acting as a antenna or something. i dont got diddly squat for shielding in my guitars and there fine.well i got a couple P90s guitars i painted the pup route and controll cavity with de humming cinductive paint but hell even it might be snake oil. just sayin man.

The copper really quieted this down back in the 1980's....
 
well im just bustin ur chops Robert but i wonder if maybe its to much copper.hell im half deaf.but i do like your Strat the way it looks.those Gibby 57s what makes it,plus that Tortis shell guard
 
Nosie Reduction.....We all know copper tape is effective...even aluminum tape is found on the back of Stratocaster pickguards...and the claim that twisting pickup leads aids in noise reduction, but lets go deeper...what about ferrite rings or clamp-ons on the pickup wiring under the pickguard????
 
What size would you guys say a common 4 wire pickup conduit measures??? I'm shopping for some ferrite clamps as an experiment....
 
INTERESTING!!!!

Plugged in the Gibson...same cables, same settings, same distance away and ZERO noise....

It's definitely in the Strat....
 
Ok,

I swapped 3 different pickguard/pickup/input jack combinations (GFS, Gibson, DiMarzio) into the Straocaster tonight and it makes the same noise with every one. I swapped cables, put the amp in different outlets...no change...BUT...I can plug my Gibson into the same setup and walk all over the room with no noise....SMH
 
maybe a wire or somethings touching some of that copper.

The copper is a good thing...

I actually ran the guitar with the pickguard wired up, but upside down so I could wiggle everything around. I also added new, heavier input jack wiring and covered them both in shrink wrap. I also moved the position of the tone cap...which was originally on one end of the tone pot...to the middle leg, according to a Seymour Duncan diagram, with no effect. The wire that joins the volume and tone pot made some noise if I touched it, so I shrink wrapped the wire. I also lifted the shields on both pickups and the noise remained.

So now I am thinking, maybe it's an issue with the amplifier and the Gibson is quieter by virtue of its lower output pickups????Strat Pickguards.jpg
 
Well....It's not the amp per-se...

The guitar makes that crazy buzzing even through my VS265. I changed outlets, moved the amp to different locations, added longer cables....still has that noise

Man I am truly baffled by this one....
 
Was quiet with DiMarzio's....reasonably quiet with the single humbucker....but last night, I put the DiMarzio's back in and it was noisy...same noise on three different amps and cables!

Frustrating!
