just cause i don't(or ain't) know how to play 12 bar blues,well just cause someone can't play it doesn't make them a bad musician.
...It's 12 bars of a minimum of 3 chords; it's not rocket science.

I've had nothing but good Guitar Center experiences. Of course, I don't go in everyday just to sit around with my paws all over their property, I go in with a mission having done extensive research on a product and I either get what I need or I don't.
You people who complain sound like you expect the young kids who work there to know everything about instruments and gear. As far as I'm concerned, it's the customer's job to do the research and decide whether or not something is of use to them. The only GC guys I ever need are the cashiers.
And maybe the guy with the ladder to get the nice basses off of the top of the wall. He's helpful too.
