I have an American Fender Jazz with S-1 Switching and I am thinking about replacing the stock pickups with a pair if Nordstrands. Only thing is, I am not very clear on which set to order. I read the descriptions on the Nj4, Nj4sv and the Nj4se pickups and I am not further ahead. My choosing pickups experience is very limited. Which set would be a better fir with the S-1 Switching or should I get rid of the S-1 Switching. Would it be possible for someone to describe how each set sounds? Thank you.
