I've bought dozens of sets of Labella flats in the past 15 years, I use the .49 to 1.09 set and just love them to death. They produce incredible fundamental tone and last forever. They're not cheap, of course, but they aren't as much as, say, Pyramids and I like them more. Anyway, a few weeks ago, I bought a new set and started to put them on one of my Guild Starfires. As soon as I started to tune the D string up to pitch, it snapped at the bridge. As I said, they've been very reliable for me so I was surprised. Also, it should be noted, my basses have wood bridge saddles so there's not much chance of a burr- a splinter maybe. Anyway, I called Labella and spoke to a super friendly woman who apologized and asked me to send the set back to them (not "return them to the store" which is what I expected). They sent me a new set right away with a really nice letter apologizing for letting me down. They got them right out to me, too. I figure any company can get a bad string and one out of hundreds of strings on my basses isn't too bad a record, but I was really struck by how well they treated me.
