Thinking strongly about dropping a new pup in my trusty P bass. My first requirement is that the pole pieces are flush with the top of the cover. After that, one that sounbds fairly balanced - something that sounds on the vintage side but will not change the fundamental sound of the bass. Lastly, it must be a drop in replacement/standard sized pup. My short list is- 1. Fender Original 62 - (I am a fan of fender reissues basses) 2. Bill Lawrence P-46 - (seem to get a lot of run here) 3. Nordy NP4 - (love the nj4s for jazz but never played a bass with their p-pup) 4. SD spb-1s - (well regarded, easy to find, inexpensive) Thoughts? Thanks.
