I'm a relatively new ukulele player -- my ukes were new when I got them, and I've only been playing them for a few months. Anyway, I haven't yet had to change the strings, and I was beginning to wonder if there are signs of string wear -- short of the strings actually snapping -- that indicate it's time for new ones. For example, do they become so stretched that they're slack even when they're in tune? Anyway, if you know of any symptoms that it's time to replace the strings, or if you think that strings are fine until they do breakm please let me know. Thanks!
