Re: Buzz on 5th fret D String
If you fret the fifth fret and it buzzes, then it is likely actually buzzing on the sixth or higher fret. Check that none of those frets past the fifth are sticking out more than the others or have come loose and if they haven't, then you can just raise your bass side bridge-action a half turn or so. Loosen off your G & D strings a little to make it easier to turn the wheel.
