I've had Fender 9050 flats for around a month now, and I'm loving them! I was kind of weirded out when I first bought them (I was expecting them to be *flat* ), but I love them! They sound great in the mix, and seem to get better with age. I'm definitely going to keep using these for a while. I was also thinking about trying out TI Jazz Flats, but I didn't know if I'd like them, and I don't want to ruin a good thing. I also love the sound of them with a pick... I don't like that clanky sound, but if I cut back on the tone a little, I have 0 problem cutting through. Also, it keeps people from slapping on my bass. So I was wondering if anyone else uses them, and if they felt they were limited tone wise by the lack of treble. (I"ve just been jamming with friends, so I don't know how they'll sound once I go back to school).
