Pentatonics at first (I think just like almost everyone learning lead, right?)
Then now more chromatic. I just feel i can basically play anywhere i want (my ears want) but more or less based on the pentatonic. So like start pentatonic, then go slide/bend/wank around and go back to pentatonic again and end on how i'd end in a pentatonic
You should check out marty friedman's instructional.. i think the one before the 99licks one.. Really teaches you how to solo, instead of just showing you some licks. Like how to follow the chord progression instead of just sticking to the key using arpegios.
