I hope this is the right forum to post this. My new guitar showed up today, it's a Gibson and I love the thing. However, as I played it I noticed that when I play the G string at the 12th fret, the note fades out quickly. There is no sustain at all, it dies out in about 2-3 seconds. It's not a fret issue, I checked it with a fret rocker, I raised the action and I loosened the truss rod. (The neck was very straight when I got it.) It does not do this when I play the note with a slide, and it does not do it when I bend the B string up to the same position. Is there a fix for this or am I going to have to return this otherwise awesome guitar? EDIT: I think it is a fret issue. Thank you everyone who replied with great advice and insight.
