I play covers on a Furch acoustic guitar in pubs. I break strings once every 5 gigs or thereabouts. I play Elixirs, but all my back up single spares are Daddario... What is there to say about a guitar string? Quality - yes, this is a quality product, lovely to play and it sings, but not too brightly - which is just how I like it. Perfect for a replacement string when you've broken one from a relatively fresh set. It doesn't stand out of the already played-in strings. I've stocked up on a few!
