I put a set on today...very happy so far. Certainly less tension than the LaBella's I'm used to, but don't be run off by that, they aren't noodle-ish, and I'm a dig-in type of guy. They're clear, even, and the note does kind of sing, as someone mentioned previously. Not an incredible amount of sustain, which is fine by me. Though I've not been able to try them on my full rig yet, they sound great through my slightly crappy practice amp and an old viva Analog 360 pre-amp. I just wish the gauge was bigger. A .100 gauge E feels tiny to me. Maybe I'll get used to it. I'm very curious to hear how they sit in a mix. And at 38 bucks, it was worth the experiment, as opposed to 80 for the TI's. That said, I've never played TI's so I can't at all compare the two. Someday.
On a side note, what led me to them was a botched used string deal here in the classifieds. I was trying to buy a set of TI's, and wound up with some Roto's (an actual honest mistake, the seller was horrified, refunded immediately and told me to keep the strings). But anyway, Jason from BSO helped me figure out the actual identity of the strings I had purchased, and it took awhile, so I'm thankful he is here in this forum, seemingly at our disposal (it was like three in the morning when I first emailed him, and we kept up back and forth until around five). That's some damn fine customer service, especially considering I hadn't actually bought anything from him in the previous/current circumstance. He was extremely patient and very thorough. And then he mentioned these strings. I bought them right away. I'm going to keep them on and see if they last. The true test. Thanks Jason.
P.S. I think they're GHS, but that's just a guess.
Edit: Playing them again just now, I want to take back my comment on the sustain. It holds for longer than I first gave it credit, for good or bad.
