I have played bass for... 21 years now?

. (keep in mind, the last 11 years flew right by). And owned 5 different, great basses.
My favourites were the:
-Cruiser/Crafter 5-string, shaped in a Rickenbacker style, with two MM humbuckers and active EQ. Got it for 200usd used, very nice one.
-Epiphone EB-0, bought new. I loved it to bits, though; a thicker neck would make it perfect.
If I were to get another bass (I have none now), it would be a cheap/(budget "violin bass", with the real hollow body. Strung with flats.
It might look "cheesy", and seem like it would only work for certain styles. But; it's so easy to play- and gives "the" bass sound, for my use and ears, atleast!

.
A bit "OT"- try a set of flatwounds on your bass. Maybe a size lighter than the rounds you'd use (because of added tension).
Fresh flats got a beautiful harmonic overtone range, and also a much more musical bottom end, I think. They also feel nice under the fingers!
Good luck
