I have the old school ibanez sr400 w/o the preamps was wondering what pickups should i put in there? it's p/j config, which drastically reduces the availability of the kind. I wanted Bartolinis or Fralins in it, but it seems like i can't... unless there's a way of combining a single pbass pup and jbass pup together. so basically, i'm asking if anybody knows if there's any good pickups in the market with p/j configuration or can i mix and match from single pups. also, i want to wire these into three pots.
