I agree, Metal Method has a great system. The Basic Course is excellent for beginner and intermediate guitarists. The Speed Kills series is absolutely the best for the serious shredder. Is there a better guitarist on the planet than Michael Angelo Batio?

I don’t agree that YouTube and other free sources are the way to go. You need a step-by-step program. If you jump from one video to the next you’ll find a huge gap in your understanding of guitar. Basically, you’ll always be puzzled by the fretboard. If you don’t go with Metal Method find a great private instructor. There’s no substitute for a great teacher. I prefer to study Metal Method’s programs and to take private lessons. That’s the best of both worlds!
