Actually, most guitar aren't shielded at all !
So how to make your guitar absolutely noiseless, you ask ? Simple.
Thanks to Mr Faraday, we know how to stop interferences from getting caught in your pickup signal.
A FARADAY CAGE !! w00t, go science !
You will need basic tools and supply:
- A guitar (duh)
- Hands (duh)
- Adhesive Aluminum/Copper Tape (I went with the copper tape, it's classier ;p ).
- Soldering iron
- Multimeter - This is crucial. Without it, we don't know if we did a good job.
- Phillips Screwdriver to remove the screws from the pickguard)
- A laminated card (to flatten the tape)
Please forgive me for any translation mistake, but feel free to correct me !
Step 1: Removing the electronics
Once the strings are removed, unscrew your axe's back plate, in order to desolder the ground wire connected to your stop-tail/vibrato. Note: This is not necessary, but things get waaaay easier if we do this.
If you don't have a back plate, like me, you might want to unscrew the front plate (pickguard).
If your jack is not in the same cavity as your pickups, etc... Desolder and remove it. Same thing, not necessary, but it helps.
WARNING: Write down the position of all wires you desolder, as well as the position and direction of the pickups, if removed from the guitar/pickguard/whatever-they-were-attaches-to. If not, you might not put it all back together properly, and your guitar won't sound like it used to.
