You don't hear a thing. It's just you, your guitar, and the realization that you're playing something so hot that no one can touch you. Cultivate those moments. The nineties, man, it's the nineties. Chick songs are out.
Depression is in.
The E, Bb, A progression is pretty cool too. Just go up to your cranked amp, move the guitar around some, and you'll start hearing noises. There's no need to bother perfecting this before you hit the stage because you never quite know what you're going to hear. In fact, they'll enjoy the opportunity to do a little yelling. I could've driven a Mack truck through that lull.
