The ultimate in terms of guitar lessons on DVD!
I use it for a year to train me on electric guitar (I have a basic electro-acoustic). I'm amazed by the quality of course: progressive, diverse, very clear.
Available only in English, but if you practice a bit, it's quite accessible U.S. (we understand).
I prefer to train alone at my own pace, and I must say it's great.
There is a set of 10 DVDs, a vigntaine lessons (real, with over several years, demo videos and video workshop, etc.).. There are also two DVD with music accompaniment.
Online courses I have tried often confused or very low quality. Otherwise it's the way with a teacher but it's not the same price. With the experience I would do that choice again!
