I've had my g string break twice since I got my new acoustic which has only been about a month or so. It is breaking right down at the tuning head. So I'm not sure what it could be. I use wound G-strings and it is really going to annoy me if it breaks frequently.

Any thoughts on what might be causing it to break??

You say that it's broken in the same place both times. That's a strong indicator that you should look around that area for any problems. It's possible that there's a rough surface, nick or sharpened edge somewhere that needs to be smoothed.

If it's breaking right at the machine-post make sure there's no rough edge on the pressure-side of the post-hole and that you have at least three or four turns around it when you change strings. (A piece of very fine sandpaper rolled into a small cone and used in the hole's edge might help if it is.) If it's breaking at the nut, or between the nut and the machine, make sure the nut-groove for the string is wide enough (It can be expanded slightly if necessary by using a piece of the same guage old G-string running it back and forth almost like a file.). You might want to try a bit of graphite in that string-groove for lubricant to make sure it isn't sticking as you try to tune or tighten it. (A bit of graphite from the tip of a pencil should do it.) Hopefully some of this helps.

Ok thanks guys. That helps alot. I'll give those suggestions a go. I really hope it doesn't become an ongoing problem as it will really piss me off. I'll let yas know if I find the problem.
