So the more research I do the more I realize that I don't want to take my gutiar to a tech to do this. I've decided to give this a try myself. This will be my first shot at guitar wiring and I'm starting out pretty big. As things become more and more complex, I'm not confident the guitar tech is going to get things the way I want. I think I'm getting very close to a wiring diagram. Here's what I came up with for my electronics
Gibson 490s in neck and bridge
Dimarzio Super 2 in middle (I'll route out a spot for it)
Fishman Powerbridge Piezo w/Powerchip and 3 way switch (which allows magnetic, piezo, or a mix of both)
3 switches to go between parallel, series, and coil tap on each pickup (still not completely convinced on this. North/South option instead?)
The thing I'm having the most diffiuclty wrapping my head around is how the swicth works to coil tap. I can follow the parallel and series and understand how that works. I'm having difficulty with which pickup should be south which north, and if they should be selectable between the north and south instead of parallel so that they work better in unison.
I suspect that the center pickup will typically be used alone while the bridge and kneck often used together. The Dimarzio will be hotter than the other two and don't know how it will blend with the Gibsons. Once it is done and hear it I'll get a better idea of how it will be used together and hoping they will work well together, but I'm willing to live with using the Gibsons and Dimarzio separately.
Here's my diagram. If anyone sees any issues with it I would appreciate the feedback.
The Gibsons wires are South start=black, south finish=green, north start=red, north finish=white
The Dimarzio wires are south start= green, south finish = white, north start = red, nrth finish = black
