so I have logged enough time on these I think to say if I like them or not . first off let me say that the only strings I have had on my jazz for the last 2 years are labella flats , the same flats to be exact. I ordered a set of high beams the same time I orderd a fretless neck, I loves them right away , the clarity was awesome the feel, tone , I could not think of anything I did not like about them . after a bit more than a month of a hour or 2 a night give or take they still sound pretty good. the brightness and zing kinda started to fizzle out, I might try to clean them to see if I get some of it back but I can see me changing them every 2 months or so. I can think of a lot of things that I have spent 20$ a month on that I did not enjoy as much as a fresh set of hi beams. are these my new string? who knows , but for the next while they are.
