5 Stars
All time favorites, brilliance, attack, clarity, stamina.
My go to strings, every time. They sound like no other, with an extra high/mid brilliance that gives a serious bite. They also last longer than any other kind I've tried in my 25yrs of playing. I love the balance that's offered in the gauge span, super comfortable to play. For reference, I'm tuned g#d#g#c#f#a#d# on a 98' rg7620, and the 11-58 set is perfect for me, some extra give especially on the bottom end, which I prefer as a dynamic bendy player.
