I'm swapping a Nordy dual coil in place of the FatStack on my Regenerate Bass. The FatStack currently in the bridge position has a coil tap switch in place. Questions regarding swapping this switch to tap the coil on the new Dual Coil. Fat Stack (As wired now) White to Bridge Vol pot, Red to middle pole on switch, Black and Gray wires to end pole on same side of switch. Other pole on same side is empty. All poles on other side are empty. Dual Coil The Dual Coil has Red, White, Black, Green and an additional silver unshielded. Any idea how to wire the switch so the DC Nordy (ordered to be wound Parallel) is Dual Coil and the switch taps it to Single Coil?
