Ok... question time! I just wired up a Telecaster with an Area 58 in neck (no cover, routed the pickguard to fit) and a SD JB Jr (made a custom mount for it) to a 4 way selector (for series at position 4) and a Bourns Dual pot DPDT (yup, two actual separate pots in one and not a blend) for coil splitting both pickups with the split position and HB position each having their own cap value. Problem is... without a coil split the selector isn't working correctly. Position 4 is Neck only (should be series), Position 3 is Neck (which is correct), Position 2 is Neck and Bridge (which is correct), and Position 1 is still Neck and Bridge (should be bridge alone) The weird thing is when I pull the switch to split coils, the selector is perfect so my solders should all be absolutely fine there. Anyone have any ideas? It's a conundrum. I followed Fender's diagram for the 4 way selector. Don't pay attention to that loose black wire, it'll be removed shortly. The white wire leading to the DPDT is the Black and White leads from the DiMarzio Area 58. Please, don't give me crap about my wiring unless it'll actually help the situation. The thing is buzzless when plugged in and sounds delicious. This is the switch wiring diagram I used. Addendum: It seems that when the humbuckers are enabled, Position 4 (supposedly for series) is actually splitting out the bridge north coil in favor of the south coil.
