After doing some research on various setups for me Ibanez AS53, I've decided to change the pickups to SH-1 59's. I want to add a DPDT switch to each pickup that goes Series/Coil/Parallel like on this guitar. Is it possible to add a third switch that will allow for in-phase and out-of-phase switching as well, or is the wiring too complicated to make all of these things possible?
