D'Addario Electric Guitar 3 Pack Environmental XL Regular Lite, .010 - .046, EXL110-3Dstar rating 5GaryDecember 17, 2009I've been using these strings for years, and i've only had a "break" during a gig maybe 4 times. I'm so in sync with these strings and their longevity, that I know from playing when it's time to change them out. And since I'm lazy about changing strings on 5 guitars, these strings give me the long distance tone I need.
