The book itself is great and has a lot of Mr. Big's Greatest Hits. There are some that are missing (a lot of the power ballads) and I'll probably end up buying another book.
My only issue with the book is the way the tab is laid out. It seems like they were trying to save space length-wise (probably to compensate for the fact that bass and drum tabs/scores are included). It's most evident when looking at two or more notes played at the same time (i.e. double-stops or chords) the notes are not lined up evenly (as they normally do). It's also a little hard to follow since the riffs, fills, etc. aren't labeled and laid out like I'm used to seeing them.
Overall, it's a good book for all the bedroom players and probably an even better book if you're going to take any of these songs live.
