As a professional guitar player, over the years I've tried an endless amount of different guitar string-brands. I've come to find that the Rotosound electric guitar strings are the ones that have the right balance between fresh sound and longevity and are simply my brand of guitar strings. That being said this, of course, differs from player to player and it all depends on your expectations from your guitar strings. If you're into the British sounding 60s music these are likely to fit you.
Of course, Rotosound make all the standard string-sizes for all the standard string-instruments. I can recommend these to players of all levels and think Rotosound make great guitar strings, plain and simple.
