Famous guitarists mostly only play specific expensive brands because they are endorsed by them. Any professional musician can make the cheapest of instruments sound really good. Maybe a note is missed here or there and the sound is not as good as it could be but it will still be way way better than an average player.

Here is Satriani playing on a terribly setup guitar [1] His only comment at the end? Oh, that was a little painful.
