I have a bass with two musicman style humbuckers and a three band EQ. It has a 5 way position switch for different coil positions and it is the same coil switching as a HH Musicman Stingray. Right now, there is no way to get single coil sounds or a Humbucker & Single Coil sounds. I was thinking of modding my bass to install some switches to get every tone possible out of the bass. I was thinking either four on/off switches for each coil (1-4) and possibly another switch for Series/Parralel or two four way switches with: Coil 1, Coils 1&2 (Humbucker in Parralel) Coils 1&2 (Humbucker in Series) Coil 2 and the same for coils 3&4. Could anyone suggest any wiring diagrams for me to take to a luthier or different wiring with switches.
3-way pickup selector switch 3-way coil select on each pickup series/parallel switch independent volume control on each pickup master volume control You could also replace the two independent volume controls with a blend. No tone controls in diagram, but it would be easy to add one. Best bet would be a master tone if needed since the switching options should provide more than enough flavor.
