Shoot... I'm not worried. I'm a born n' bred flat wound guy; in 50+ years of playing bass, there are only 2 kinds of rounds I've ever voluntarily put on a bass - and left them there. One is hex core GHS Boomers. The other is TI Jazz Rounds. But, spiffy as the TIJR's are, on the bass they're on? Not much chance of them showing up on any of the other 22 basses... Flats and Tapes, for them...
The Jazz Rounds are on my '94 Gretsch Broadkaster; a bass that fought me for... well, more years than I care to think about. Every flat wound I tried on it - and I tried a
lot of them - just sounded like inarticulate mud. The TI Jazz Flats were probably the best of them, but... slightly inarticulate mud wasn't what I wanted. Tapes? Uh... no. As for rounds? Well, if I wanted a hollowbody Gretsch
guitar? I wouldn't have bought the Broadkaster... Until the TIs, the best rounds were a set of La Bella Super Alloy 52s; they managed to sound like a
baritone guitar...

I'd bought a set of Jazz Rounds by mistake, 3 or 4 years ago (doesn't pay to be in a hurry). A year ago, out of... desperation, I guess... I thought; well, I've tried everything else; might as well try these things. And... they worked! The Broadkaster now sounds like a real bass guitar. Maybe a
hair brighter than I'd like from a big hollowbody bass; but, that's what the amp's controls are for. And, yeah, they don't feel much like other rounds, either. Best of all; none of that squeaky finger noise that irritates the Bejeezus out of me...
So... on the Gretsch? Yeah, the TIJRs are definitely the cat's ass. But, on any of my other basses? Nah; the bass that wears Boomers will keep them. So will the bass that wears Tapes. As for the rest? They'll keep wearing the flats they're wearing now...
