Yea I no that you can stick in a note thats not from the scale.. I know a few cool patterns that involve that... just from how slash has done that in the past.

When it comes to writing songs... Im a simple guy. I doubt slash or most of my fave guitarists no about neopolitan chords :confused:

All of my fave bands base there songs on pretty standard chord progressions.

Heh, If Im ever a famous guitarist I wont get much credit! I'll be another kirk hammett one trick pony guy.. but i dont mind.. I enjoy what I enjoy.

Its just really really daunting learning theory. It seems endless... like I either learn it all or none.
