Hey man, welcome to the site. Sounds like you learned the way I did, although I took lessons for about 6 months about 12 years ago. I mostly learned by reading tabs and learning songs by Van Halen, Guns N' Roses, Metallica, etc.....just all my favorite bands. Then to learn more advanced technique's, I started learning Dream Theater songs, there is so much technique involved with their music...

Any techniques in particular you wanting to learn?
