When you fret a note, and get buzz coming from the fret behind the spot you are playing, what is the solution? I have already raised the saddle, (no help), then gave the neck more relief, which improved the situation. No other spot on the neck does this, so I don't want to just keep on adding more relief to the neck. Maybe I should have taken out some relief, I don't know. By the way I know its the fret behind the note because fretting both spots, i.e. 2 fingers, but same note, makes it go away. In this case, it is 6th fret on the B string, but I had it happen on another bass's E. Thanks for your input!
