Plays well, sounds great!
I just put a set of these strings on my Sterling By Music Man (SBMM) S.U.B. Ray5 bass. They sound great and impressed my sound man who was also a bassist. He was impressed with the jazz sound of these strings when I cranked up the treble.
These strings also are much better to fret than the original Ernie Ball strings that came with the SBMM. The Ernie Balls would buzz a lot, but these Rotosounds would not. So, better sound and better playability means that these strings cannot be beat! Only disadvantage: stings have somewhat a rough texture. To me, the advantages outweigh this disadvantage. I will stick to this brand for my SBMM for now on.
