hey everyone -

I have a pretty specific question (which is kinda rare because everyone seems to go "how can I sound like Vai") anyway...

I love playing, listening to and trying feebily to solo over the blues. I know the major pentatonic pretty well and the blues/minor scales... My question is, are there other scales I should be messing with? Also, I was told that most of soloing is about following the scales up and down the fretboard and also making chords. I've seen a few licks that just don't seem to follow the rules or their not a scale I know...

can you combine them to make other riffs?

thanks all!!
