Originally posted by Alex:Technically speaking, if I wire together two normal single coils the single hums double up. But most strats use RW/RP middle pickups which are reversely wound and reversely polarized. Now if I wire a normal single coil together with an RW/RP one the two single hums nullify each other, no matter if in parallel (strat switch positions 2 and 4) or in series (that's how they invented humbuckers). But of course I must be careful not to wire anything out-of-phase which would result in a thin and useless sound. Thankfully there are a lot of guitar wiring diagrams on the internet. A series / parallel switch is often labeled as "useful", and the Fender American Deluxe strat has even got a stock switch for this. I just can't get any decent sound files and I'm curious if it could serve as a substitute for a "real" humbucker. If not I might just wire one of the strats SSH.
I just pointed the risks of out-phase and humming problems, but I see you're aware 
I posted it before: There's no wizardry in assembling a strat, it's almost like assembling IKEA furniture plus a little soldering. The trickiest part is the setup. But I really love doing all that stuff myself. If I bought a preassembled strat I'd most likely want to change pickups, pickguard, etc., so I'd have to deassembe and reassemble it anyway. On a partsocaster I can choose the parts I want to have right from the beginning; a preassembled strat has got most likely the wrong colour, the wrong pickups, etc.
