Hi guys,
Since noise (hum and hiss) is irritating the hell out of me when playing my axe (California strat with tex mex) I want to give the shielding a try. I'm not new to guitars cause I can set it up the way I want to but I havent got into the electronics yet. I'm going to try it on my old copy strat first.
3 questions:
1. When using the Bridge-on switch will the neck-bridge and neck-middle-bridge pickups be in parallell or series? In other words will it sound like the out of phase tones on 2 and 4 or?
2. Does rewiring affect the noise alot? since I'm still new to this I would like to try the shielding and ground to foil first
3. Can I shield my jack cavity or will the metal (jack plate) interfere?
I'm waiting for my copper tape to arrive now, guitar has been totaly dissasembled and ready.
Thx for the help

3. think of the rewiring to eliminate ground loops, as being a further refinement.
you will still get benefit from doing the shielding alone.
you will get a bit more reduction of hum and noise, by also using the better wiring practices.

Allright lads, lets see what you think of this. users.pandora.be/snowy/Hiss/Pickup%20Noise.mp3On this I first selected the neck pickup and then moved my strat towards the PC, next same thing on neck/middle (out of phase) And no I do not have a CRT but a TFT users.pandora.be/snowy/Hiss/Noise%20without%20EQ.mp3The above is without EQ and using 2 or 4 position (wich are the only positions I can play without the loud hum) I can EQ by reducing trebles n mids but that only camouflages the issue. users.pandora.be/snowy/Hiss/Noise%20with%20EQ.mp3I will try the bridge-on switch but still wondering if it will run in parallel or serie with the others those laughing with my "heli sound imitation" will not receive a free plectrum signed by my grandmother Greets from Belgium

I feel completely ignored here. Very depressing since I try to post my issues as detailed as possible. Thx anyway, I'll seek help elsewhere then.
Keep it going fello guitarists.

Sorry Jimijunior,
i can't speak for anyone other than myself here, but i couldn't quite understand what you were asking.
some of the questions seemed contradictory and confusing.
i guess i was just being a little lazy, hoping someone else would help you.

Hi Jimijunior,
Trying to answer your question 1:
With a simple bridge-on switch the pickups will be in parallel. It will sound a bit different from positions 2 and 4. Bridge/neck will be broader and all-three will be smoother. And neither of them will be hum-cancelling if that is what you mean, when you say "out-of-phase". Probably you're confusing reverse wound and out-of-phase. Out-of-phase is a different pair of shoes. On your guitar every pickup combination should be in-phase. If you want to get out-of-phase sounds you'll need more switches.

Jimi - thanks for the Pm. First, I liked the playing, nice work. The sounds on the second clip with positions 2 and 4 seem great - and that would show that your wiring maybe basically OK.
The first clip, with just the noise is hard to learn much from, because we cant hear it along with the sound to hear the relative levels. Could you post a clip with the hum, and then with the same settings, start playing with just one single-coil pickup? All normal single coil pickups hum to some extent, and the amount of hum is greater than that which is screened out by shielding. Computers, even without CRT's can be a bad source of it.
I also hate soldering to pots, so I solder a wire to a washer, put that around the pot shaft and use it as my ground point.
Most people don't shield the jack cavity, but there is no reason not to do it that I can see
John

John hi John, if most people were as careful and conscientious as you, i would agree unconditionally. but there is a limit to the clearance in the jack cavity. if one isn't careful, it's very easy to short the hot side of the jack with the foil. so, i agree, on the condition that they are aware of the potential problem, and exercise the necessary caution. unk

Thx for the response guys, I really apreciate it.
I have just finished the rewiring on my old copy strat but I dont hear any difference, but thats probably due to something messed up in there. Thing is, when I switch to neck pickup I only get a loud hum and no sound but when I switch to neck/middle all is fine. I do get the same hum as before though. My Cal strat also has the same hum after shielding (not rewired yet) so I'm in doubt if its even worth the trouble anymore. This noise issue has been bugging me for a very long time and I'm so fed up with it. Instead of actualy playing my guitar I'm always trying to find this noise free signal. I would love to hear an example from your guitars amigos, what the noise level is like when using clean or high gain settings, without gate and without holding the strings. Anyway, thx again for the response lads.

Have sheilding question for my strat. Guitarnuts mentions someone using copper foil from Michaels craft store. I bought the material. It is 100% copper leaf sheets. I sprayed cavity and new pickguard with adhesive and applied the foil. This foil is very thin. Does anyone have experience with this material? Is it effective? Thanks
