I really enjoy these strings on my passive pj bass. The .112 set on my bass sounds more warm than bright. And the balanced tension is totally awesome, no more consciously thinking of plucking harder or lighter on the strings. And the tapered e string is also awesome. With all the other strings I've owned, I had to nearly max out the saddle for the e string to get proper intonation. With the tapered e, I had to move the saddle more forward. Also, they don't feel super rigid, they feel firm but have more than enough flexibility to send the pitch sharp if you fret firmly. Basically I enjoy these strings with a flat eq on amp, and tone maxed out or cut out. But when I set up the eq a little bit, they really sound nice an full sounding.
Other strings I've tried(fender nickel plated 40-95 and 45-105) were far too bright for my taste out the box and onto the bass, without cutting the tone all the way out and dropping a little mids and highs from my amp eq. And with those strings, I'd often applly jojoba oil(it structurally resembles sebum, that our body produces) to the strings to remove some of the brightness.
With the circle k strings, I like how they sound new. Considering I prefer used strings to new, I think I'm going to like these strings more as they age. I might replace them with a .124 set, but as of now I'm totally satisfied with em.
Thanks circle k.
