In the solo of the song master of puppets by metallica of course,i've been practicing the really, really fast one. I have the book for it but i was wondering if there's anyone that knows how to play it. There's a part in the solo in the middle where kirk makes the string really squeal with the trem bar. i have no freakin clue how to play this. It says right underneath the quealing *This note produced by pulling stg. off the edge of the fretboard, "fretting" it against pickup. i don't really have any idea how that works and would really want to know. please tell me!@ $@!#
