How about getting him a personalized guitar pick? You can have his name or initials engraved on it, and he can use it every time he plays guitar as a reminder of your love and thoughtfulness. Alternatively, you could get him a guitar lesson with a local guitar teacher he admires, or treat him to a ticket for a concert by his favorite band or guitarist. Another idea could be purchasing a new guitar accessory, such as a new set of strings, a guitar stand, or a guitar strap that he might have been eyeing.
Or you can get him a star map with the date of your anniversary.
