These are definitely some of the best strings I used! It's incredible. I have gone through Evah Pirazzi Gold, PI, and all the top brands, and these stood out to me. It has such a warm, round, gutty tone, and it is perfect. I also play a different style, south Indian Classical music, and for that style, this is the perfect marriage. Now the one thing I have to do is wait. Hope the sound does not deteriorate.
