How long does it take to know every note in the fretboard? Also, is there any way to learn the notes faster or just know a note just by looking at it in the fretboard? I've noticed that it does not matter if I know a bunch of theory if I can't track the notes. I can't make a mayor chord a mayor 7th chord if I do not know where the 7th is, so I need to learn them. Any tip?
