Seymour Duncan SPB-1 Vintage for P-Bass : Metropolis's user review
Used set of Fender Precision + Jazz Aerodyne.
Compared to the original microphone (Korean?)
The mid-bass dominate.
It sounds a little oldschool.
I find the artificial harmonics less beautiful, but the sustain is much better.
Coupled with SJB1 is really not bad
Finally, I join the opinion below the bass becomes more personality, a register Roots / vintage, and loaded mid-bass. This will not necessarily suited to play fast and modern.
