Best Answer - Chosen by Asker:

Just bend and vibrato the 3!. Don't play the 5!. I guess that's kind of the pitch that you bend up to from 3, but don't play it!. The tab on that part is wrong!. I just learned the riff for you!. I watched the video i the beginning and this is what the guitarist is doing!. Pretty simple!. Don't let the tab confuse you!. I'd never heard this before and learned it!. Just trust your ears!.
