How 'bout TI (Thomastik Infeld) JF344s (Jazz flats)?
Well balanced, thick, warm and punchy on my Jazz Bass. Bright, but not overly bright and I've noticed less sustain on the notes fretted higher on the neck than typical roundwound strings. They are pricey for the initial investment, but get better the more they are played. Their longevity can be measured in years.
I just put a set of the Jazz Flats on my 55-94 - WOW! They're staying on the bass. Nice full, articulate, deep sound - not zingey at all, just like I wanted.

Is there something you don't like about the Ernie Ball strings fenderbluesdude? They're pretty good strings I hear. Are they too thin sounding? Break too often? Too bright sounding?
Some of the tone things can be adjusted with the bass tone controls and the amp settings.You list a fretless Fender J as your instrument; there's a lot of tone variation you can do with just the bass's controls. I mean, Jaco used something similar (though he had those Acoustic amps back then and an 18" cab) so it might not be just the strings. Just find a company you like that make strings that are not too expensive, are always available and don't break that often. Then see if you can get your blues/rock sound from the amp. It almost seems, from your amp setup, that you might be wanting a little more bottom. You might think of stacking the 2x12 on top of a 2x15 or even a 1x15 and get a thicker sound.
