Hi! I'm thinking of the way to wire a standart Jazz Bass. I have the following diagram that allows the following: 3 modes for each pickup: on, off, out-of-phase Series/parrallel switch Pickup switches are supposed to be 3-way Mustang switches. I also plan to replace Series/Parallel switch to Mustang switch in order to have kill switch in center position. What is missing is blend pot. I'm curious is it worth adding a blend pot to such configuration? I've heard that some interesting tones can be achieved while using phase switch, but adding just a little amount of phased pickup.
