Like the box says, get these if you want that original Fender Precision Bass sound.
Made well, prewired to a new copper ground plate - solder in 2 wires and you're in business.
At one time I had active pickups in this 30 year old Made In Japan P bass. Run by a 9 volt battery (I routed a battery cavity under the pickguard), they were bright and "attacky", and I really liked them at the time.
Then, after some years of using those pickups, I reinstalled the originals out of a desire for change, and was amazed by the great tone. I didn't recall loving the original tone before, but this was great. That was at least 10 years ago.
Then I bought these recently to replace the original pickups. Because the original pickups sound great to me in this bass, I did this primarily 'cause I've upgraded everything on this instrument over the years - better bridge, better tuners, and I now did the electronics, thinking I could improve the instrument's tone even more.
While I can't say, "wow - it sounded awful before and now it's amazing!", I think maybe it's got better definition and clarity than before. It certainly has the traditional sound I'm looking for and I'm not wishing I hadn't bothered. I need to play and record with it more to form a clearer opinion, but so far it's everything I was hoping for, tone-wise.
I did note that the new pickups look like they're maybe manufactured better than the old stock ones.
All in all, these are the real deal, provide original spec sound, and they're made well and easy to install. It's hard to know whether you'll improve your sound in a way you'll like in any given instrument when you change pickups. But if you like upgrading your gear and experimenting, it's always worthwhile to try.
