if i do the coil split with the tone pots, lifting one pot splits one pickup? so if that pickup is selected by my 3 way toggle switch then its just a single coil? and if im in middle position with both split its like a strat in 2 or 4? am i warm?
That's the gist of it, although it would be possible to split
both pickups at the same time with a single push-pull pot, if you wanted to - gives you less options, but keeps it simple(r).
as for series/parallel, i aint got a clue what that entails?
In a humbucker the two coils are normally wired in series for that typical thick humbucker sound. They can also be wired in parallel, which gives a thinner sound, more like a single-coil, but still hum-cancelling. You could use push-pull pots for series/parallel switching, but in that case you
would need a separate push-pull pot for each pickup, because it uses more of the switch connections.
HOWEVER, as both Twinfan and Wez have already mentioned, it will be a struggle fitting push-pull pots in an SG because the body's too thin (I'm assuming it's a Gibson SG, not a Yamaha?).
