Ultimate Rhoads

Hey guys, I was playing the intro of Crazy Train (Randy Rhoads Tribute) with the tabs from GuitarPro (http://www.ultimate-guitar.com/tabs/o/o ... ar_pro.htm)
and after the 032000-054200 part randy goes like:

---------12----------------------------------
-12b----12----------------------------------
---------------11b--11b-11b-11b-11b-11b
----------------------------------------------
----------------------------------------------
----------------------------------------------

These 11th fret bending sounds don't sound like the one's in the live version (they are different) the live version... Does Randy use a special technique for this, or aren't this the right tabs for this Crazy Train intro version?

try using artificial harmonics on the bends. and from there when you move up to the slow bend on the 4th fret set your volume on the lead pickup to 10 and rhythm pickup to 0 and flick the switch back and forth.

Yeah, those are def. artifical harmonics. Those can be a little tricky if you're a little new to guitar. Those are the little squeals you hear in Zakk's playing all the time.

I'm not so new to guitar, but I've never played 'artificial harmonics' before
Thx alot.. !
