The quality is good. No hummm, no hisss. Not noisy at all. Very good product. But, you know, the sound is very subjective. I like the sound of the bridge pk. I prefer other pickups for the neck pk. So I have a mixed set on my fret-less jazz bass, with this bridge pickup. That's why I rated okay. I should rate separately the bridge pickup as good and the other one as poor. But, anyway, not my preferred set of pickups.
