Building my parts caster and got the the pickups wired up with a 3way. Adder neck and Fralin Blues Special in the bridge. Neck sounds great. Bridge sounds pretty good. Middle sound weak and thin, and to my ears, sounds out of phase. Any ideas? I think the adder is reverse wound...? Wiring is like this: Adder: green/black to ground. Red to switch. Fralin: black to ground. White to switch.
