Bartolini has really poor documentation. I would like to put each of my Bart XXM45C Quad Coil Humbuckers on a three way switch that will allow me to chose form Humbucker, Single Coil, or split (p or inverted p-style). They will be going to the blend know on my Bart HR 5.4 wiring harness. Has anyone done this? How do I wire it? Any diagrams? Thanks in advance.
