FYI about SBMM Ray5HH electronics

Hi! First time on this forum. Just thought I’d share some info about the electronics in the Sterling Ray5HH..

I recently purchased one with the intent of taking out the preamp, and rewiring it for passive operation with 2 volumes with push-pull pots for series/parallel wiring, and 1 master tone. In the process I recorded some info.

The 5 way switching configuration is kinda weird.
– bridge (series)
– bridge outer coil and neck (series)
– bridge (series) and neck (series)
– bridge inner coil and neck inner coil
– neck inner coil

The two pickups are identical with an impedance of 7.15k ohms in series. The coils closer to the neck are south polarity, north polarity for the other coils.

The pickups have 4 conductor leads.
– green: north start
– white: north finish
– black: south finish
– red: south start

There’s is black paint in the control cavity that I assumed was graphite shielding, but I found that it was not conductive when tested with a multimeter, so I added some copper shielding. The pickguard does have aluminum shielding in the control area.

I hope this info helps! I was looking around online for these kinds of details before purchasing, but couldn’t find anything.
