I've tried a lot of strings for my son's Acoustic-Guitar, but the D'Addario became our favourites! The realization came late, that D'Addario not only make good E-Guitar Strings, but also strings for the Acoustic-Guitar. They came well packaged. After putting the strings on my son's guitar, there was immediately a total fresh and clear tone, that fits wonderful with his guitar. Also they stay very good in-tune! The durability is also better than the other strings we've tried before. My son plays these strings for more than one year now (no, not the first package ;-)) and he won't change them!
