Constant buzz on 8-11th frets G string

hey TB, I'm having an issue that I can't figure out. I'm getting bad buzz on the g string 8-11 frets. I've tried almost everything now. I have done a leveling twice and crowned them to my best ability with what I have, tried truss adjustments more relief, less relief, neck reset, adjusting action will make it go away slightly but it needs to be way higher than I'd like it to be. I took it to my tech and we straightened the neck out and raised the action and it just feels like the neck moves a lot it wasn't too bad, but the neck was too straight to where I was getting buzz on the lower frets so I added a little more relief. Everything in that general playing area of the 8-12th fret it's very buzzy on all the strings and feels very low but everything up past the 12th fret is totally fine. I think I'm going to be stuck with this buzz as long as I own this bass it seems like! Any help or tips would be appreciated!

 

Thanks for the reply. Yeah I check for Loose fret ends with a piece of wood and nothing they seem to be in pretty good. I even tried tapping them down with a fret installer and a light hammer and no major changes.

 

I had the 2nd fret replaced a while back and my tech did a leveling and everything was fine. I even leveled it again to make sure and still getting the buzz. I have no idea what is going on. Maybe a bad string?

 

That's what I was thinking. I've concluded a ski jump or maybe those frets are too low for some reason. I'll have to measure again just to be sure. I hope it's not a ski jump but usually they occur down near the very end of the neck where plate meets (from what I've seen anyway).
