Just purchased a Classic Stack Plus middle pickup and wired it to a push/pull switch to split the coils as per the diagram that came with it. I'm happy with the overall tone but can't say that I find much difference in tone, switch up or switch down. I've gone back and checked the wiring and it matches the diagram. First question, am I expecting too much? I'm thinking of making it an in phase/out of phase switch which I have done with other Humbuckers. Second question, is there a place to find a diagram that labels the pickup wires or an in phase/out of phase for this pickup?
