I've been using the TI Jazz flats for some time a really love them on Precisions. I had a set of some Infeld Superalloy Round Wounds from a bass I bought and tried them on a Jazz and was really surprised at how they had some mid thump. I'm really liking flats for the deep mids and was impressed how the TI SAs didn't have the kind of low-mid hollowness typical of most rounds. (If you disagree with my appraisal of rounds that's fine, but that's not what I'm interested in exploring in this thread. ) I was wondering if anyone has tried the TI Jazz rounds and the SAs and how they compare. Also, are the Jazz rounds less in tension than the Flats? Any personal experience would be greatly appreciated.
