Watch "Rock Discipline" by Petrucci.
It's as basic as it gets to doing any kind of virtuosos.
I own a couple a vids, MartyFriedman's, Petrucci's, Paul Gilbers, Some YngwieMalmsteen.. (his is pretty crap.. he's too much of a showoff to be a teacher.), ZakkWylde (great pentatonic stuff, but nothing more), Don Mock, Victor Wooten (I'm not a bass player, but it's interesting to watch, mix of bio/discography and his "thumb-techniques"), also have Joe Pass for some jazz, and lots of concert vids that I missed out back in the days because I was too in to rap, and some concerts that I missed because they just don't have them in Canada.. or near my range. (i.e. G3 2005)
But I found "Rock Discipline" the most helpful.
Of course there's more than just listening/watching lesson vids, but most likely all the basic techniques are there and it's suppose to help you get on your ways. your "unique" ways, that is.
