just finished shielding the inside of a Epi Les Paul copy. I was just wondering if the 400v isolation capacitor was for safety, or if it actually served a purpose in making the shielding effective.
also, there are 4 wires coming from each humbucker... do the signal ground (green) wires go on the signal side of the isolation capacitor or does it matter???
thanks

they don't call it an isolation cap for nothing! Its there to prevent dying. Noone likes dying...

The cap does provide a measure of protection - the effectiveness and necessity are in contention (see the MANY posts in this forum to decide for yourself).
Omitting it will not affect the effectiveness of the SHIELDING.

amf17, Hi, and welcome to the NutzHouse. ;D Yes, it matters. Providing that you installed the safety capacitor....... You should hook the braided shield wire to the non-ground side of the cap, and the signal wire that is intended for ground to either the ground itself, or to a switch that will place it at ground some time later in the circuit. (Some switching schemes need to manipulate the signal ground wire for connecting two (or more) pickups in series.) Running the signal ground wire through the cap to ground is not a good idea, tone-wise.  No cap, no problem. It's a safety thing, it pretty much takes care of a rare instance that may come about, or it may not. Jimmy the Greek is laying the odds at something like 500 to 1 against it ever happening.

weird. i'm 99% done shielding the body of a strat and was wondering the same thing with the cap since i'm about to tackle the wiering.
I've never tried soldering tin foil together.. i wonder if it'll be a big mess and 3 hours wasted if i try..

jm, Tin foil - no problem, tin solders easily. Aluminum foil? No way, that stuff won't solder worth a hoot in a holler, don't even bother trying.  Chances are pretty good that you don't have any tin foil in or about your domicile, it's aluminum foil that most folks get their hands on. A "pressure" fit will work though, just drive a short screw through the foil into the wood, and wrap your wire around the shaft (and under the screwhead) before driving it down snugly, that'll be a good connection.

yeah, aluminum foil. i grew up calign it tin foil.
so tape on the points where i want good contact with the foils and the good 'ol screw head trick with the ground.. I gots too many wobbley pops in me now to even consider a soldering pencil. I've picked them up by the wrong end a few times. white skin and one less hand for a week are not good.

jm,
Unless it brings out the "nursemaid" in your local groupies, then it might get a bit interesting. ;D
