So I have a Fender Player Precision bass and I absolutely love its playability and weight, which are two things that had me worried about getting a P-Bass but now I play this one more than my Sire J. The thing is that I am not loving the pickups that came with the bass, I think that they voiced the pickups for the new series of Fender basses for a more "modern" tone and they lack the bass and low-mids of a more vintage pickup. The demo of the American Professional in the video below sounds a bit similar to mine ,which I also have strung with flats. The bass sounds a bit "stringy" or bright for my taste, although it is not a bad sound, I am thinking of getting new pickups for mine and I am considering the Fender Pure Vintage 63 or the Seymour Duncan SPB-1 to get a more vintage sound to play blues rock and soul. Has anyone tried any of those or have any other recommendations?
