How do you wire the SSS Silo Spec up to the Silent Circuit when the set installed is not RWRP? Can you give a detailed blow-by-blow? So I can print it out and pass it to my tech? I remember you mentioned this before in brief passing. Would like to be more clear about it. I'm getting noises on my positions 2 and 4 for the Fender CS69s, and I remembered you explaining this before.

Thanks!

The wires from the Silent Circuit are wired to the ground of each pickup. Basically the hot goes to the wiring harness, the ground goes to the SC (it provides out of phase noise which is canceled out).

The way it's normally wired up, the neck and bridge pickups have their ground wired to the blue wire from the SC. The RWRP middle pickup has its ground wired to the violet lead (noise is out of phase with the blue wire).

So, for a non RWRP middle p'up, just wire its ground to the blue lead instead of the violet. Same point as the bridge and middle are wired up to.

RWRP = reverse wound, reverse polarity.

Basically, RWRP pickups use a magnet with the polarity reversed. The windings around the coil are also reversed. These two opposites (both magnetic field and winding) lead to a current that's in-phase with the other pickups. However- stray noise that's picked up by the coil (the windings act like antennae, picking up stray electrical noise) is out of phase (b/c the windings are backward).

So when you combine the RWRP pickup with a regular pickup (neck or bridge in this case), the guitar signal is in phase but the noise is out of phase. The noise is thus canceled out, which is what you hear in positions 2/4 of your single coil equipped guitar.

Same principle with a humbucking pickup: the second coil is RWRP with respect to the first coil. When you combine them the signal from the strings is summed from each coil, but the noise is out of phase and is subtracted out.

Thanks Beej! Much appreciated!
