I bought indie flats about 2 months ago- they are not good. Kurt is an awesome guy to deal with and I feel bad talking bad about any of his products, but these strings do not make the grade. I am not super picky about strings, and usually use webstrings because they are inexpensive (they do sound good though). The indie strings are very dead, but not in a mellow broken in sort of way, more like when you pluck the string nothing really comes back at you. I have a warmoth gecko 5 string, and the B on this is massive. I have used labella 5 string flatwounds before and they are amazing. Anyway, the B on the indie set was beyond dead- it sounded like I was palm muting (or maybe deader). The other strings did not have this issue, but they are dead. Kurt was very cool when I emailed him and wound up sending me a labella b to replace the dead indie B, but that really highlighted how inferior these strings are. I put the indie strings on my bass on Thursday because I just got the bass mute and was in a flatwound mood, and getting through the gig was tough (it is a motown/ r&b band, 4 hour gig, perfect for flats and a bassmute). Anyway, if someone wants to try them out PM me and I'll send them to you (I know it's tempting after my rinigng endorsement!!), at least the 4 strings- I'm going to keep the labella b for future use. Anyway, I took the chance on these and Kurt did offer to refund my money if I didn't like them, but since he was cool about the B, I figured I would chalk it up to research. If you're not on a 5 string, you may want to try webstrings flatwounds (only a 4 string set), I have been happy with their roundwounds.
