I was in GC the other day, and one of the sales guys was playing a jazz with black strings. It sounded great... deep and warm, but with enough treble to keep things interesting. When I asked him what they were, he told me Labella Jazz Rounds. As far as I've been able to find LaBella doesn't make a string string called a Jazz Round, nor any black coated strings at all. TI makes jazz rounds, but they don't seem to be coated either. I guess they could have been bootzilla's, but I didn't think those strings had a reputation for the type of sound I was hearing. Anyway, if anyone has any idea what strings these might be (and where I could buy them), please let me know. I think they'd be perfect for my fretless p-bass.
