Hi UGB ! I'm freting just behind the Fret (I'm sure I'm doing it right) and this buzzing is coming even when its played open, and till the 4th fret (when played till the 4th fret) and after that its not. I'm not sure about the tuning machines, How should i check that ?
I cant take it to a technician, as there are'nt any here

All the other strings sound fine.
