If you were a rockstar, you probably wouldn't smash your guitar at the end of the concert cause you would feel kinda bad for what you did after it, amirite?

But you have to admit, it would be really bad ass at the moment.

Dude my guitar is my baby ;) lol I could never hurt her like that

I don't really think it's done as much as Hollywood would have you think. It's always in movies you see it, never in actual live performances. The only way it would be practical would be if you bought a piece of crap guitar and used it the whole show, which would make the show sound worse. So there's really no point in it.

EXACTLY i could neeeever harm my guitar haha
