Black Diamond Black Coated Phosphor Bronze Mandolin Strings  

Why don't more people use these? They get rid of all the annoying "new string" overtones and sound clean and pure from the time you put them on , till the A string gets hard to tune (the only indication they are going bad). They have great bass response and mellow the highs without muting them. On my mandolin (an eastman 615) nothing sounds near as good. How long do they last, you ask? With regular playing of an hour a day, these strings last about 2 months, depending on weather.

These are some nice strings, they sound great... but I was unaware that they have loop ends, which makes stringing my electric mandolin difficult. I broke both of the e strings putting them on but the rest have held up pretty well.
