I am looking for any recommendations for guitar strings. I have used Ernie Ball Slinkys since I started playing guitar, but lately I have had nothing but problems with them. The balls at the end of the unwound strings seem to slip slowly over time until it falls off and the string pops out of the bridge. I have had this with 4-5 sets of Ernie Ball strings now. The most recent was just 30 minutes ago on a set of strings I had on for less than a month. The string doesn't break, the wind at the end just comes undone. It is also has a tendency to make the string go flat as it slowly slips so end up constantly tuning the guitar. The problem seems to happen randomly. Sometimes I will have a set that lasts until the strings wear and I replace them. Then maybe the next two sets have issues. Its driving me nuts.
