I'm looking into possibly wiring up a Jaguar for a friend with a series option. I've been doing some reading and found some conflicting information. One site said that if you wire up two pickups in series one must be RWRP from the other to make it work. Another source said they have to be wired the same direction. So what's the truth? I did a tele with a series option (the 4 way switch) a few years ago and wound the the pickups so that they would be RWRP. So it must be the same, right? Thanks in advance.
