I've been trying out a copy on the PS3 for a little while and it seems pretty good.
The only problem I've had is the game seems to have problems detecting what note I'm playing on the E sting in one of the mini-games, I'm thinking I might have to adjust the pickup toggles until I find something that works. Other than that the only other real problem is there is a little bit of sound lag. The game actually recommends that you run your consoles sound output directly into your sound system to reduce the lag.
Be warned though, it is aimed more at beginners so if you're already an accomplished guitarist you're probably not going to have as much fun with it.
