By all brands of guitar strings I've tried during my years in music, it has always led me back to these, D'addario.
The reasen I choose D'addario is because you will never get disappointed. The tone is round and clear and it stays in that shape for months!
If they tend to get dirty, they are easily wiped of with just a simple clean cloth.
Another thing I like about these strings is that they can take very much hard handling. I can bend them, scrape them, pull them and just beat the hell out of them. They still keep playing as if I've never touched them.
The condition capability is perfect!
If I were to recommend any strings what so ever, I would strongly recommend these to anyone whether you are a jazz, rock or metal guitarist!
These strings will never let you down!
