CDs are great. Find a Victor Wooten or Stanley Clarke CD perhaps. Find out what kind of music he likes. New strings are always wonderful. Or just a gift card to your local music shop. That'd be good times. I know giving a gift card can feel thoughtless, but going with him to the guitar shop would more than make up for that. Plus, it's worth it to give a musician ANY excuse to head to a guitar shop. Seriously.
