High quality strings, in both the sound and feel. light gauge, making it easier to play. Perfect for beginners, and professionals alike. Great for bends and fast playing. They're strong strings that last quite some time, I use them on my Epiphone Les Paul, and the sound is quite bright and clear even without plugging it into an amp. I believe the steel-plated core makes the string harder to break and snap during playing, without affecting the sound quality at all since the outer wiring is where most of the tone from guitar strings come from. Overall, very great set of strings. I would definitely recommend these.
