I have used a good tutorial called guitaralliance.com They take you through all the facets of learning the guitar right from the begining.

They send you regular newsletters and lessons and new riffs to learn etc.. You can also log on to the site and pick out any of their tutorials at random once you have subscribed.

I did pay to subscribe can't remember how much but it wasn't exspensive about £15 I think.

Good Luck
