The Gradebook could be a bit bigger, of all things in the handle table, it falls in various grades hard to see the finger positions. The songs, however, are not written in notes but in tabs, so it is not necessary to know what note to play straight.
The bag is only made of fabric, therefore, hardly suitable for longer transport.
All in all a good playable instrument and of course, a considerable part of the collection of any Zelda fans (even if this is not musical).
