Ok, I'm treading in new territory here so I need some help. I just received my new BRICE 6-string fretless (cheap ebay special). The fit and finish is really nice actually. The only problem is with the low B string. First off, I've only played 4 string basses. Never played fretless, and never have used flatwound strings. All of the other strings sound good and punchy, but that low B string just sounds dead. It has a significant decrease in volume compaired to the other 5 strings, and it sounds like that all the way up the fretboard. Almost like it's being muffled or something. I raised the action on it, and still nothing. Does this sound like a problem with the bass or just a bad string?
