I put some TI JF345's on my Stingray 5 a week ago and I have really been liking them alot. I always thought of flats on an electric bass for R&B or old school types of music but I know lots of folks are using them for lots of different types of music these days and the TI's are very versatile strings and I really like them. Well, as much as I like TI Jazz Flats I never thought of using them in the US Army Jazz Band that I play in because I usually either use an upright or a rather bright sounding electric bass for more modern stuff. Well today I used my Stingray5 with the TI Flats and man I am impressed. These strings really provide a nice warm tone that just cuts right through the low brass yet stays nicely in the mix. It has some upright qualities in the tone while still retaining an electric bass clarity. My bass is a whole new instrument with these strings. I still like my DR's and Ken Smith Rounds but they are not getting as much playing time these days. I now know why they are called Jazz Flats.
