So I need some new strings, and I wanted to try the new flatwound set whose development has been influenced by our own Mandohack. I ordered from JustStrings, and began to string them up - alas, the very first 4th string snapped right through the core of the string. Rats! And not at the loop end, but at the peg head. Never seen that before. So I wrote a disgruntled (but polite, I hope) note to JustStrings (and D'Addario) to say that I was surprised by this poor quality - loe and behold, JustStrings sent me an entire NEW SET by FedEx!! Wow! Customer for life! Plus, I like the strings. Heavier than most flatwounds I've played, but a nice punchy tone to go with the silky feel. They have a load of sustain. Hope they last- we'll see. But I thought this a story worth sharing.
