Pros - excellent balance between the strings in regard to tone and overall feel; smooth surface; very high quality; great clarity without too much high-end racket; clear B!
Cons - none
This is a great "middle of the road" string in terms of tone, compliance/stiffness, tension, etc., and it will suit a fairly wide range of preferences- simply season to taste. If you like ultra-bright sizzle or dub thud, look elsewhere.
The B string is very well balanced with the others in the set. I was pleasantly surprised because I had abandoned the use of tapered B's many years ago after frustration with another brand. I also normally go lighter with B's, but the .130 has excellent pitch clarity and setting the intonation is much easier than I expected.
After using DR Sunbeams and Dunlop Super Bright nickel, these strings have a slightly stiffer feel and required a minor truss rod adjustment to get the relief set in the same ballpark. I also noticed that I could set the string height a little lower than the previous sets- definitely tighter excursion and longer sustain.
It is evident that a lot of care went into manufacturing this string and I will likely keep using them on my parts P5 bass, perhaps going for the lighter set.
