this is a bit off-topic but let me say it anyway. no offense to those who feel that everything beyond restringing and tuning must be done by a luthier. anyone who is serious about guitar playing should also be serious about the maintenance and setup of his guitar. stated differently, every guitar player should maintain and setup his own guitar and, maybe, dress frets or refret when needed.
it's like driving a car. beyond knowing how to drive, one must also know how to and actually do basic checkup and maintenance work like: inflating, changing and rotating tires; checking and maintaining proper level of radiator coolant, brake fluid, and clutch fluid; replace windshield wipers, spark plugs, busted lights, worn brake pads, and dirty air filter. in fact, the law requires that you check these basic things before driving a car. otherwise you will be held liable for negligence if any of these things fail and causes damage to third parties.
basic guitar maintenance and setup is a dirty job and it takes time. it doesn't require a lot of talent but it requires some amount of patience and perseverance. there's is also great satisfaction learning and doing things yourself and you will learn to appreciate your guitar more as a musical instrument, by how it plays and sounds and not so much by how it looks and feels.
here's an old related topic that may be interesting:
http://talk.philmusic.com/index.php?topic=181594.0i have nothing against luthiers. i have never been to one so i don't know about their work. i do everything myself. a friend of mine has a huge collection of tutorial books and videos. i learned by reading a lot of books and by watching all those old tutorial tapes (guitar hospital series by dan erlewine, mark arnquist, harvey citron, etc.) and the new tutorial dvds which anybody can get from amazon. the specs of a standard setup (distances of all parts relative to the other parts) are in the books and it varies slightly depending on the author. but it's important to know what makes a good setup and how to get it. only then can you make adjustments according to your own preferences. i like the old books and videos better where they used common and simple tools effectively and efficiently. there is also a lot of information in the world wide web (with emphasis on the “world wide”) which you can study before you actually try doing things yourself. the bottom line is you will know if you want to learn and you will learn if you are not lazy. you learn by reading and observing and you gain experience by doing it. you only have to overcome your fear of doing the first step and the next steps.
a guitarist should go to a luthier only for major jobs that require extensive work and special tools (read: expensive tools) like repair of a broken truss rod, broken peg head or twisted neck.
