Bartolini PBF 57

I would like to start off by stating that I am a Bartolini fanatic. I use Bartolini pickups in all of my guitars and basses.
Passive humbucker. No impedance specs due to pickup construction. As in my previous review of the PBF 77 if I knew the specs I would not have purchased this pickup.

Ibanez Mike Mushok Baritone
Bridge position.
Bartolini PBF 77.
Not sure.
PBF 77 was not a good match with the gain level I use. Unacceptable overtones on treble strings.

Lower output than PBF 77. Higher output than stock pickup.
Tech 21 Trademark 300
This pickup like the PBF77 has a lot of bass. Still too much for my taste. Still had many overtones on treble strings. Not a good match for what I do.

Would not buy this pickup again. I will get a different Bartolini.
I have been playing for a few years. I am self taught and use a bizarre open tuning. Too much gear to list here.
I love the build quality of this pickup. I hate the sound.
I wish it sounded like all of the other Bartolini's I have.
