I bought an AO 50s tele about a year ago, and I play it religiously. No kidding, I would guess that I have it in my hands at least three hours a day (usually while I'm also doing other things, like hanging out with the kids). It doesn't happen often, but there have been a couple of times over the last year when I'll set my guitar down in the evening, with no audible string buzz, and pick it up the next day, only to find that one string or another is more prone to fret buzz than it was the night before. Again, it's not happened often; maybe twice since I've owned the guitar. But, for instance, I played the guitar all weekend, but when I picked it up yesterday afternoon, anytime I bent the G string at the 7th fret, I'd get a severe buzz that would completely mute the string. It definitely was not happening the night before. I adjust the set screw in the saddle a turn or so, and the problem is solved. I'm just curious to know if this is common.
