Thank you for your restraint and brevity. While I am not quite as Fender averse as you, the Jazz bass can do one as far as I'm concerned. While the P bass may be uncharitably described as "agricultural", the Jazz is way worse to my eyes - big, fat, melty lump of a body with a skinny neck, so ungainly looking - I get nothing of the "upscale" model that Fender was going for even back in 1960. I don't get why they're so revered, I've owned one (when I was figuring out what I wanted from a bass), I've played several and I just don't get it. I have never seen a Jazz which makes me think "I must have that". Hard no from me.
True boring = everyone liking the same things.
