I already have a basic understanding of what guitar repair guys do. I've been setting up my bass and my friends' instruments for years now. How do you become a luthier? I'm not trying to open my own shop or build my own guitars but I want to have a job working on guitars/basses at a local music store or a place like Sam Ash or Guitar Center. Can anyone give me any information on where to start? Do I need to go to school or get an apprenticeship with someone?
