My local GC tech does a great job doing setups. He knows exactly how I like them. A little odd, because I've never bought a guitar from GC. I just decided to give their tech a try at doing the setup on a new guitar because my usual guy was backed up. GC tech did a great job so I've stuck with him. I'd probably use my regular guy for anything more complicated than a basic setup, though.
Suspect you can't paint all GC techs with the same brush...I happened to get a good on - at least when to comes to a setup .
