Hi Ryan, welcome to the group and congrats on the Brown Bass. As Keith and Mica said, Joey's post is a great starting point. While you're there, check out some of the other posts in the FAQ and Must Reads sections. Middle of the neck is usually a truss rod adjustment. Mica is THE authority, but if it's just a bit of buzz on the 9th fret of the G string, I doubt you would need as much as a 1/4 turn; 1/8 or maybe even less might do it. I also think Olie has a point that there might be a fret level problem; but try adjusting the truss rods first, that's the usual place for something like this. On my Essence, a change in humidity will show up with a bit of buzz on the 8th fret of the G string. I slight adjustment takes care of it.
