ping

It's usually the nut BUT it could be either the string settling at the bridge pin (might have been pinched and not pulled into place when you strung the guitar) or the pin itself lifting a fraction.

 

I'd give the nut slots a quick run through with a bit of old string (obviously guitar string and size appropriate to each slot used as a file), lube (bit of pencil in the slot works just fine), detune the offending string and reposition it at the bridge pin then retune and see what happens.

At this time of winter heating season. with very low humidity, below 40% in your home, sometimes buzzing and ping can occur because your guitar top has dried out, pulling the strings closer to the fret board. Also, low humidity can cause the neck to move..often backward..which also brings strings closer to the fret board, causing such things as ping and string buzz. It does not take much movement, and may not be easy to see with the eye, but very small shifts in the wood, due to low humidity, or high humidity can cause a good guitar to go out of whack, leaving the owner wondering what went wrong. Proper humidity as measured by a hygrometer (walmart, or radio shack) should be between 45% and 50% either inside the room or inside the case, or both. That level humidity in the guitar wood will stabilize the wood and neck from shifting. Wood is exactly a kitchen sink sponge. It swells when wet, and it shrinks and dries when it becomes dried out. I suspect if your home is heated, your humidity has become consistently low, causing the possible problems of ping you mention. Rectify the humidity, by adding a guitar humidifier to your case, and, or room, and measure it by the digital hygrometer. Only then should neck adjustments be made, or other alterations, such as nut slot filing, or bridge lowering be done, because once a guitar is returned to the proper humidity level, it will come back to normal. It may take a week or to restore the humidity to the wood of your guitar during the humidification restoration period. Take care not to OVER humidify as this will make more problems as well....that's the reason for the digital hygrometer...to monitor a 45% to 55% condition. Good luck! ....Cold winters..and dry winter heating can create Havoc on wood guitars, and even damage them irreversibly. And it can occur quite often to any acoustic guitar during heating season.
