I switched out the stock strings for some mmiller Dunlop, ever since I now have buzz on the first couple frets on the d string and all fret after the 12th fret on the A string. If anyone could give any advice it would be greatly appreciated. I've tried adjusting the action a bit to no avail. I've never really messed with the truss ever on any of my basses.thank you all. I have a v7 ash 5
