I just finished a gig. It went pretty well, aside from my freaking D Strong Tuning Peg Breaking... Again. This is the third time this year it has happened. I've replaced it both times before. I assumed the first time was a fluke (maybe got banged hard while traveling or something) but the second time I figured something was up. I made sure to string it properly and checked the setup to make sure there wasn't something crazy happening. So now in the middle of the set I notice my D string seems a little flat... I go to tune it and it won't tune up any, only down. When I try to tune it up the key turns but the post will not wind in the string (by that I mean it doesn't move at all.) Tuning down works just as it should, except maybe a little too good... I'm absolutely confused and frustrated... The last two times they this happened when I tried to tune them up the post eventually snapped free... I rarely play on the D string (I'm of the play higher on the neck school), so it's not like I'm wailing away on it! Any ideas at all?
