As a side note, I once had a set of half-rounds that I wrote off for the very same reason, but when I decided to dust them off again for a second look I discovered they actually suffered from the same highly-correctable issue as a lot of flats: Some type of gritty gunk or substance left over from the manufacturing process that can be removed by either (1) playing them a lot or (2) simply running them through a slightly damp cloth until they get fully clean before installing them on the bass. After I did the latter they were super smooth, almost like a worn in set of flats. Personally I see a lot of people knocking the texture of certain half-rounds or flats and I wonder if it is just this type of thing; these days I always clean off flats before installing and they always end up being nice and smooth.
I went through this exact same experience with a set of D'Addario Half Wounds back in '21.
I took them straight out the box and installed them. They sounded pretty meh on that bass and their feel was just gross too. Upon a closer look, I realized that it was because the strings were still covered in machine oil & tiny metal bits.
So I took them off and gave them a thorough cleaning with some iso until a white rag could dry them off without getting dirty. It took awhile. About 40 minutes or so iirc.
It was well worth the effort. Now they were almost as smooth as regular flats. Once I installed them on my '15 Squier VM60s Jazz (with the later Fender Designed pups, not the awesome Duncan Designed ones that the earlier VMs like my '13 VM70s Jazz had), the tone was finally up to scratch.
Up until then, I couldn't get those pups to sound really good with any other strings that I had tried and conversely, I couldn't find a bass that really sounded great with those particular strings either. However, they were totally the ticket for that bass and are still on them today.
Wondering how these compare to Ernie Ball Cobalt Flats? The descriptions sounds similar, not quite flat feeling, a little sticky to start and more like worn in rounds.
I was wondering that as well. Specifically irt the high end.
I have a new set of the Cobalts on hand to try on an AmPro2 Jazz that currently has a set of Chromes on it. I have a couple of basses with the Chromes but tbh, they always leave me feeling a bit underwhelmed. Reasonably good but not great like the "right" string set would be.
...Strings make such a big impact and I’m slowly learning not all basses sound their best with your go to favorite strings....
100%! I figured this out awhile ago. Imo, it's well worth the effort and much cheaper than endlessly replacing pickups.
At times it can be a time consuming process to find the set that gives a given bass its best voice. As it was with the VM60s Jazz mentioned above. That was a bit of an ordeal but a definite exception to the rule.
