Learn the notes of the Bass Fretboard. Great for beginners or those that never learned the notes.
First select a note.
There will be 4 cards shown on the scree, one for each string, with the note represented on the staff for that note.
Next select one of the cards, and it will show the location on the fretboard.
Fixed issue with images on the 4th string being shifted down one, giving the appearance of flat notes.
