Just a small tip for the nails.
Well, let me explain it over here, because the rain didn't help much.
You get a small rectangular size sandpaper, then you place it covering around the E string, and shoeing the B and the G string. My advice is to cover the D, the A and the last E string. You don't have to if you don't want.
It's a slight difference but helps enhancing the sound.
