My first set of half-rounds so I can't tell if I've just got a bad string or 'they're all like that.' The B has almost no harmonic content. Nice thump, but no mids. I've had lots of different sets from a few manufacturers and this is the first that's acted like this. I know it's not the bass - it's the string. If they're all like that, I'll learn to live with it even though I don't like it, because for the most part, the sound works with what I'm going for. Probably I'll just order up a replacement single from BSO, but was looking for others who have BTDT.
