I took these pickups to replace the original mark without a fender-like defrette, there is no other microphones as these on this bass is the first time I change pickups .
sound has become much more precision, and dynamic right now I use a net with ropes course and more, giving her a hard, velvety.
The bass and mids are very present, in fact, these microphones may be more suited to the low frets ... I'll have to test, but J.
