hi and welcome to chordie.
As I have used and still using it, I can recommend jamplay.com loads of videos to watch and learn from. This site does require a feee though, but I would say it is worth it, whether you are experienced wanting to learn a new style or a complete beginner I tihnk it is good.
Also there is a guy called Justin on the net somewhere, I hear he is good but I dont know much about him, other maybe could tell you about him.
Good luck with your learning
Ken
