I am retrofitting an original Gibson EB-3 choke circuit in my Epiphone EB-3. Read somewhere that the bridge pickup need to be reversed phased if doing this. Anyone experienced with this? While removing the original wiring harness from my Epiphone EB-3, I noticed the bridge pickup has a 4-wire (red/white/green/black) + shield cable. The green/white wires are taped together. I guess I could do a phase inversion or series/parallel by adding a mini-toggle switch.
