The key with a PJ bass is to get a hotter, high output J that can match the P output volume. Yamaha does this pretty well, the Tony Franklin is great because it uses a Dimarzio model J, etc. Most stock Fenders come with a useless low output J that doesn't match up well, so lots of people end up thinking they don't like PJs but in reality they just haven't had properly matched pickups.
