Hello, I have a fender aerodyne jazz bass and it has the P/J pickup configuration. I heard something about pickups being in either series or parallel and it got me curious. Does anyone know what my pickup wiring would be in by default? (series or parallel?)

Does it really make a difference sound-wise? Can someone describe to me how they sound?

And a diagram of for each of them would be very helpful, should i decide to play around with it...

Help guys!
I use:
Fender Aerodyne Jazz Bass (non-export model)
Behringer Ultrabass BX600
