Right, I've been here before. However.....I recently swapped back from Rotosound rounwounds to TI Jazz Flats on my Epi Jack Casady bass, and the combination is interesting (but not ideal). The Jazz Flats are make this bass TOO bassy and more indistinct, without giving the kind of punch I was looking for. I'd like advice from other Jacksters about finding a flatwound to go onto the JC which will bring back some more mids, enough bass but not too much, and which have a nice attack when played fingerstyle. A good example of what I hope for is that I put TI Jazz Rounds onto my G-Bass (which was previously very bassy, muddy and deep) and gave the bass much more of the way in mids and attenuated the muddiness which it was sometimes prone to. So far my ideas include: Fender Flats 9050's GHS Brite Flats Rotosound GS77 Jazz Bass Flats Anyone have any further input?
