I have a few basses for the same reason, I like to pick up and play the one that I feel like playing at the moment, and I appreciate things about it, and after I put it down and pick up another, I re appreciate the things that I like about that specific bass. It keeps it interesting, and it makes playing old familiar basses, fell like playing it the first time once again. But I am a collector at heart. I can’t compete with Al or @John_E , or even come close, but I like the collection I have, but still would sell some just to be able to buy others.
I didn’t read the whole thing, but the part I read about you liking the p bass, but the neck was too wide, and you liked the stingray, but had the same issue with the neck…
Did you look at the Sterling by Music Man Stingrays, the Ray4 or the Ray24 in particular? Those are stingrays, just not American made, so they don’t cost $2500, but they are awesome instruments, and they have the more narrow 1.5" wide jazz neck. I would rate the Ray4 as the Best bang for. your buck for sure. for $299, you can’t find as well constructed, great classic looking, slick, awesome feeling bass that can sound like a stingray, like a real stingray. I prefer to swap out the stock pick up, that is the one area they cheeped out, but if you cut the eq all teh way down, maybe boost the bass a little, you can still play it and enjoy it. once you start boosting the treble, that pick up is so hot it makes your ears start bleeding.
To be fair, too much treble with many basses, on the bass, the tone pot, the amp, any pedal, and or any combo of, with too much treble can make any bass make your ears bleed, so if you play your cards right, you can live with the stock pick up and have an awesome Stingray for $299, With a jazz sized neck that sounds like is more to your liking. Sorry if all that was covered already, I am catching up, lots like about 8 days back.
