I Just purchased this and received it about 2 weeks ago. Looks like a great book but this is not a beginner book. You will have to do some homework to get the most out of it. While the Tabs for the licks are in the book, the recommendation is to first listen to the song a lot and try to transcribe it yourself first. Do the lessons on transcription to learn the tips on how to transcribe.
While not necessary to transcribe the licks perfectly yourself you should at least try as it will help you to develop the skill for the future. This is a skill I need to work on. There is a lot of string bends so make sure you have your bends in tune. The first few licks look to be pattern 1 of the minor pentatonic so you should at least have practiced that and can bend the strings in tune.
If you are serious about learning blues and are Intermediate level or above then this is great book. The first lick is 5 bars long and it will probably take me a few weeks/months to get it. Hendrix was a master so maybe it will take me longer. The challenge for me will be to stick with it, push through and not get discouraged.
Also I posted this questions about Eb tuning related to learing the first lick in this book: Eb Tuning - Justin's Blues Lead book
