Not quite a zombie thread, but thought it might be worth adding another data point to the conversation.
I recently acquired a new Ibanez SRH500F fretless semi-hollow with piezo-only bridge pickups. Lord only knows why, but it comes with Chromes as the stock strings. I quite like Chromes, and (now) have them on two other basses (G&L Tribute L2000 and now a 1981 Ibanez Roadster PJ, on which they’re really good) but they are way too much for a piezo pickup, especially with a resonant body.
Anyhow, gave them about a week playing 3-4 hours most days, but they didn’t really improve — I think this bass had likely been on the shop floor for a while, and the strings are pretty well broken in — and was giving considerable thought to their replacements. Different flats, try tapes for the first time …?
I have TI jazz flats on my L1000, which I love on that bass, but I suspect that their upper-mid colour would also prove to be a bit overwhelming on the Aerium (SRH500F), and the setup on the L1000 is perfect, so I didn’t want risk that or the strings by swapping them around. The Roadster was wearing the LTFs, and while I liked them there, it seems to benefit from just a bit more tension, or something, that the LTFs weren’t providing, so I decided to swap these with the 45-100 Chromes.
The LTFs on the fretless Ibanez seem to be pretty perfect. I’m not chasing an upright tone (I have an upright for that), and that is frankly futile in any case, or even an EUB tone (I have that, too). On the Roadster, the LTFs were pretty much what has been described many times on this thread: vintage-leaning but articulate, nice but not overwhelming mids, and not too much going on up top. On the Aerium, they really open up. The piezo picks up everything, and the LTFs really have only what I want and nothing else. They have a really clean top end with no fingernail-to-blackboard (sorry Millenials and Z-ers if you don’t know what a blackboard is

) harshness, and I can open up the tone knob and dial back my low-pass filter to let more air through. I had to change the setup quite a bit, allowing a little relief and raising the action at the bridge, but the intonation is better with much less radical saddle positions than with the Chromes. The mwah on the E and A strings is now quite subtle and controllable, and more apparent but still controllable on the D and G strings.
If you have a bass anything like the Aerium and are looking for something to try, I would highly recommend the LTFs.
