I use Truefire.com
They have all kinds of stuff, but you have to pay for it. There are all kinds of lessons from beginner to professional with tabs and slow motion videos.
I have learned some really sophisticated songs and techniques using their stuff. They do have a lot of free sample lessons too.
If you wanted to take private lessons from a world class guitar teacher, but couldn’t afford it, I’d suggest you check it out.
Thanks, P-Marlowe. I haven’t visited the resource, but how do they acquire their tabs? The one thing that doesn’t thrill me about Songsterr is that it’s like a Wikipedia for guitar and bass tabs. Drums as well. Anyone can submit tabs.
