Does string cleaner do amazing things for your strings?? Does it extend the life of your strings?? I have never used any before. just wondering......
I don't think string cleaner really does much unless you find a way to soak your strings in it. Otherwise, the stuff still stuck in the grooves of your strings will still muddy up your sound.
I use GHS Fast-Fret and like it a lot. It really prolongs string's life and make them sound bright (if they are not TOTALLY dead, of course).
