Re: NEW PROJECT! NEED HELP!
I'm assuming Master Vol., Master Tone control plus two switching functions. It is possible to do this, provided that there is sufficient depth in the control cavity to accommodate push/pull pots. (Some of those S series guitars are too skinny, especially towards the outer edge of the body.)
Regarding the series/parallel switching of the two single coils. Series mode will render at least two of the selector switch positions identical to each other and one of them bereft of any signal.
Whichever position remains operational in the series mode determines what will be possible in the other positions. Series mode available at the neck position is easy to select under time pressure but reduces your options to Bridge OR Neck. Series mode available at the middle position makes two versions of Bridge and Neck available together but may prove more fiddly to select live on stage.
