if ur jus gonna play jack stuff, forget the book and learn tabs...get the song u wanna play and find the tabs for it (best site my opinion is "
www.ultimate-guitar.com" listen and play along-tabs are mad easy to read so u shoulnt have a prob...but a lot of jack's stuff is bar chords and palm mutes which take a good long time to master...try be like that by 3 doors down to get u started-that was my first and it didnt take to long...but the no.1 rule in learning is PERSERVEER! takes mad long to get good...MAD! so jus be patient and it will all come in time.
