Other instructional websites?

Hi there everyone. I'm sure everyone will agree that Riff of the Week is at least one of the best guitar lesson sites on the web. In fact, it's one of the only good ones I can find. I found this website purely by chance, and because I was a Vai fan.

The problem is, it's one of the ONLY good ones. Guitar Player puts out some good lessons though, and Guitar World can be good, if you're only into metal/rock.

There is one interesting website I know of though. It's called Mr. Fastfinger/Guitar Shred Show... It's quite unusual. You have to go there to find out. It's really just a collection of challenging and often Vai-like licks played by a cartoon.

From a bass players' point of view, Play Bass Now is an exceptional resource, though you have to be good at being able to figure out what he's playing just by watching him play the lick slowly.

So since you all obviously have good taste in guitar tuition, being here and everything, can you please share with me other websites you visit of this nature? 6 billion people+ in this world, and only one makes a truly excellent tuition site? Come on, it just has to be me.
