Default String Rattle

I have an old Norman acoustic guitar (2002). I just changed the strings and now have the G string making a rattling noise. The noise is most noticeable with capo on the 2nd fret and playing the string open (the noise is still there with no capo but not as noticeable). I can see that the bridge pin for that string is down lower than the other pins and have always had difficulty getting this pin to set. I have tried the following, non of which has any effect:

1. Switched the bridge pin with another.
2. Installed another new G string.
3. Capoed all the way up to the 10th fret.

I also looked inside with a mirror and all of the strings seem to be set up against the wood. There is something that appears to be a pen mark coming from the G string hole. Maybe this is a crack?

Any ideas or suggestions?

Phil

Buzzes and such can be hard to track down, they don't always come from where you hear them either. Check for loose tuners first, that is a big producer of strange buzz. How is your truss rod? is it slack or does it have tension on it? Could be a burr on the saddle too. Those are the first three to check from my perspective without actually seeing the instrument.

A guy over on the Seagull forum hit the nail on the head. I checked my neck relief and discovered that with the string pressed at the 1st and 12th frets there was zero relief. In fact, I had to back off the truss rod nut a full turn (in 1/8 increments) before I could get a piece of paper to slide through at the 6th fret. At this point the rattle is completely gone. I assume that this is the result of humidity and temperature. I will keep a humidifier in the case at least until the house furnace is not coming on any more. I will also get a proper hygrometer so I can measure the humidity better.
