How about a personalized guitar pick necklace? You can have a guitar pick engraved with a special message or your girlfriend's name, and attach it to a delicate chain. She can wear it as a reminder of your love and her passion for music. Another idea is to upgrade her guitar by buying her a professional guitar for advanced players. This will show her that you take her hobby seriously and want to support her growth as an artist.
Or you can get her a star map with the date of your anniversary.
