Uh... Right. Lets go though the basics of the GH guitar controller.
-Five 'fret' buttons, no strings.
-A strum bar, a button that can be pressed up and down like you would if you were strumming a guitar. Again, only one of them.
-It's plastic.
-No pickups or bridge.
It's nothing like playing a real guitar, that doesn't make it rubbish though; it's an entertaining game.
i agree, i would much rather be a real guitar hero, infact i play bass, and i put a guitar on my christmas list this year. its a very fun and addictive game to the point were i wanted guitar hero 3 for the pc until i found out that the system specs are very high for such a simple game, but its nothing like standing infront of a big speaker with the volume cranked while playing your favorite songs on a real guitar.
