Great lessons and materials. They are able to asses your skill level very quickly and then start concentrating on the things you would find most interesting. They have their own guitar material with worksheets and videos that are given during the lessons, plus anything your teacher can cobble together and scan in, which makes it very easy to go back and check what you need to do for next week lessons. There is a lot of attention to detail given to their website also. For example you can look at all your previous lessons so you can see what you have learned. I will be using these guys for a long time, great service and would recommend to anyone.
