I’m completely with you on the deaf part. I’ve always been tone deaf and now I’m all deaf. Lol
Not sure what strings you mean. In my experience I never noticed that issue. I would angle the D & G side of the J bass pick up a bit closer to the strings. But the level magnets never bothered me. Obviously the conventional wisdom is to angle the P bass pick-up to the fret board, but some knowledgeable folks on here have suggested otherwise and when I tried it I found that to be the case. Not trying to argue with you just pointing out an alternative approach to setting P bass pick ups that worked for me. Of course, I'm half deaf so what do I know.
