Watch the Open String Lick online guitar lesson by TrueFire from Play Blues Guitar 1: Quick-Start for Beginners
Playing solos will cause you to start thinking about moving single note licks around. This lick is a great one to practice on since it uses some open strings like you are used to. Don't worry if you have a little trouble keeping certain strings from ringing out when you don't want them to. Once you have worked on getting the overall lick down, you can go back and fine tune it and make sure it is clean.
