I could use a bit of help. I've got my guitar wired up using this diagram. HH. Bridge humbucker has the magnet reversed so in the middle position I get the two inside slug coils in parallel (with phase and hum cancelling intact). DiMarzio EP1111 4pdt three way switch. One vol pot no tone. I'd like to add a switch (possibly a fender s1 vol pot) to add switching so in the middle position of the EP1111 I can select inside slug coils in parallel (currently) OR the outside screw coils in parallel. There are DiMarzio diagrams that have this but without the reversed bridge magnet! Which I want to keep (they flip the whole neck pickup around to do something similar). The reversed magnet and reversed wires are confusing me. Can someone help out with a diagram that would allow me to do this. I love this wiring scheme but want to add a 4th voicing. Thanks in advance. I've emailed DiMarzio and posted on a guitar wiring Facebook group with no replies from either. Help me out TGPers!
