A friend of mine has it. He should be joining the website shortly, perhaps he'll stumble upon this topic?

Hopefully. Really interesting to watch someone else play, and see the changes in difficulty according to how their doing. Keeps the whole song interesting, as opposed to guitar hero, where you might be getting slaughtered the whole time, or doing it behind your head, left-handed (true story).

I have it for 360, a tip I have is don't always just follow what rocksmith recommends go into songs and master sections there then go back to the venue. Is easier to get better at a section to keep repeating it in Leveler at 100% mastery (which you do in the start menu when doing the leveler). If it is a harder section do free speed not leveler.
