Here's the story about aluminium shielding:

1 little hint, if you are thinking about shielding don't use the copper foil but aluminium foil.
bill has an article about the great shielding effect of aluminium foil

Where are these articles? There used to be a lot more on the website if I recall, but can't find half them anymore, nor all the old posts from Bill on the forum. Kind of disappointing really.

Anyway the guitar sounds way better w/o the treble mod, and L90's are the sexiest humbuckers ever!
Thread closed, happy end i love you all

Also insulated and combined red & green.
The rest of the wiring i took from the SD diagram.
I really suspect now that the guitar cavity is poorly shielded as fuzzy pointed out. Interesting to mention i didnt have any annoying noises when i soldered two OBL 900XL

A passive guitar circuit doesn't really "have room" for ground loops. This problem is not actually caused by the guitar and it's not really a grounding issue either, because the noise disappears when you touch guitar hardware.
BLs have superb treble response and will pickup electric noise in the room other pickups do not sense.

so maybe when you used the sd diagram there will be a problem

The other day i fit in two L90 humbuckers, which are godlike btw, into my esp eclipse, replacing two silly EMG's.

I also installed trebble bleeding capacitators on the volume pots.

Now i have a "crackling noise" loop, which isnt caused by my amp, but the guitar. When i touch the volume knobs(500k goldo),

the noise goes away. Is that a grounding issue?
