I recently bought an Ibanez Gio GRX70QA. It's a really great guitar for the money. I was going to put in a coil split switch for the bridge humbucker and had instructions on how to do so using the white wire in a 4-wire pickup. The Gio's switching is a 5-position Strat-type configuration and when I got into it, I found both red and white wires had been used as part of the switching system. I'm trying to use a two-terminal, two-position toggle but there are almost no wiring diagrams for this. I tried to just attach it in the middle of the white wire (from pickup, to switch) but this did not work and the on position just produces a hum. Is there any way I can wire this correctly or will I have to use a 6-position switch which I have on hand? Thanks in advance!
