First, the things that I don't like:
1) The CD is set up so that there is one track for all 5 styles of each lick. If you want to hear the last couple styles of a particular lick, you have to fast forward until the one you want to hear is played. It would have been much better to have a different track for each style of each lick.
2) The "country" style licks have an absolutely horrible tone. HORRIBLE. I've never heard a tone like it on any country song. It sounds much more like what a rocker "thinks" country sounds like than what country players actually play. Its really nothing more than an annoyance for me, but it bugs me to hear it still.
As for the what I like about this book? There are a some good licks in the book, particularly in the blues and rock styles. For what it costs, it is worth the price, but I own other licks books with a higher proportion of good licks in them.
