I have a 1983 Pbass that plays very well.
But I was not satisfied with the sound.
These pickups were a part of the solution (I also experimented with strings )
The bass sounds full and "expensive" but still vintage.
I have not done a real A-B test with the original pickups, this would of course be the only reliable test.
I could easily be fooling myself. But anyway, the pick ups do sound quite good!
