It's the usual VVT, 250KA volumes, 500KA tone with .047uF cap. The switch splits the pickups to the inside coils.
The body came loaded with the pots, jack, bridge and a DPDT on/on switch. Since the switch was already there, may as well use it! Coil splitting made the most sense. T pickups split to the bridge side coil, but I figured out a way to do that opposite coil split. It's cool, the inside coils in parallel are pretty close to where a Stingray pickup is located, and it does sort of sound like a passive Stingray. Plus, since it's opposite coils, it keeps it's humbucking operation!
