Thank you, thank you, I'll be here all week.
Tinny note

Note G on the first string on my guitar is tinny. All the others are fine. I just bought it about a month and a half ago at it's just been the last couple of weeks that it started doing this. Anybody have any ideas? Thanks!

Since the guitar is new I would take it in to get it setup. This will most likely fix the problem and help keep your guitar in good condition.
