I ve been using them for 10 years now, both for recording and live applications. Due to my sweaty hands I had a hard time finding strings that last longer than 2 (4hour) shows. Well made, and decent sounding strings, almost to the bright side of spectrum, they don't get slime and dirt too easy. Definitely recommend them to a touring musician and a session as well. Bonus you get an extra e string !! Cheers
