I use the first pages with high voltage. For the following reasons have not convinced me the strings: The bass strings sound good only at medium volume, but that may be due to my guitar. My feeling the strings fit together tonally not good. The change of grip you get hardly go without intrusive background noise. From the G string were already after a few days of using nylon fibers, the string looks rough and uneven. After 4 weeks, is now through the jacket of the D string. The previous strings were significantly longer on it. The beginning very common Nachsstimmen probably lies in the nature of things. After one to two weeks the mood then held very well. Maybe I'll go back to strings with medium or low voltage.
