I have a MIJ Cobain Mustang with Duncan JB Bridge and MIJ Mustang neck pup. I would like dual concentric pots so each pup will have independent volume and tone controls. Additionally, would like to be able to split to either coil of the JB, while retaining the out of phase pup option. I was thinking of three potential solutions:
1. Add a mini three-way toggle in between the volume/tone pots to switch between pups and then use one of the existing three way sliders to switch in/out of phase and the other slider to switch the JB between full humbucking, split slug coil, and split screw coil.
2. Use one of the existing 3-way sliders to switch between pups, the other to select in/out of phase options and then add a 3-way mini toggle in-between the volume/tone pots to split coils on the JB, as per above.
3. Basically the same as #2, but flip the function of the mini toggle and the out of phase slider.
Would any of these work or is there another option to achieve my goals?
BTW, I checked under the pickguard and there is no route near the lower horn to install a 3-way toggle like what you see on the current MIM Mustangs and I do no want to route the body.
