These are supposed to be the best strings out there. You're paying for the premium and you should get the best, right? NOPE. Compared to other stainless steel sets, these feel very dull. D'addario ones look and sound much brighter. Even the cheap 10€ Warlock strings are better than this, albeit with shorter life.
It would be acceptable if it wasn't for the low B string. It is BY FAR the worst part of this set. The other lighter strings are actually still pretty good. However, the low B is useless piece of crap. Not only it sounds completely lifeless, you will have zero sustain on notes, and zero attack. I'm attacking the string as hard as a human can, but still no attack. Absolutely worst string I've ever used.
Don't waste your money on this. They are good for 4 string sets but the 5th string makes this set unusable. For me the steel D'addario sets are the best sounding ones by far. If you want cheaper options, get Warwick Red Labels.
