The Fender 9050ML flats I use have a strange story. Just two weeks ago I installed them on my Ibanez GSR200EX. They forfilled all my expectations... Untill Something happened to the G-string. All of a sudden it was hardened. It produced squeaking harmonics and felt like some hard drawn fence wire. As I do have a lot of facilities at my work, I was able to anneal the strings. I took all four of them off my bass (replacing them one by one). Then I gave them an electrical anneal, by driving a current through them high enough to have them discoloured. After the anneal they were cleaned with scotchbrite to make them shiny again. An extra clean-up with alcohol made them look as new. I re-installed them on my bass. Guess what... They now sound better than before, are stable and very playable. If one of them hardens again, I will have to go back to the 'dAddario chromes.
