I am a guitar whore. I'm now up to 14 of em. I can do basic shit like intonation and bridge height but have always been afraid to mess with a truss rod, thereby not getting the same quality set up as when I drop one off. Whatever I'm currently playing the most gets the pro set up but it's cost prohibitive to get them all done.

I'd like to learn the hows/whys of knowing when to adjust the truss rod vs. bridge and saddle height. It wouldn't hurt to know how to look for problem frets and other shit that I may not know about.

I'd prefer to do it in person as I like to ask questions but if you know of a great internet source for learning this shit that'll do. I found that Specimen has a guitar set-up course and was wondering if anyone has attended.

Specimen Guitars runs a couple of courses - one is on guitar setup. Here's a link

I keep meaning to sign up for one of the setup classes but it seems like they fill up quick.
