Just gigged a new-to-me set (40 hrs. playtime at time of purchase) of TI Jazz flats that sound good with only one tonal setting. They have no top end, some mids. Incredible low end, though. Played two gigs at two venues, both with odd room designs. My bass did not seem to sound how it usually does and had to wonder whether it was the strings or the rooms. These flats feel great but are extremely limiting tonally speaking, unlike Chromes. How much time is a fair assessment?
