What the hell means "rake"? I've seen it on a lot of tabs, but don't know what it means.. Please explain how to rake..
It's kind of like sweep picking (know what that is?) only with more palm muting. Let's say, in a solo, you wanted to start on... oh... the 7th fret of the B string (complete example). To start off, you could heavily palm mute the A, D, and G strings, sweep the pick really fast across them, and then hit the 7th fret hard.
It's more of an effect-type thing, and doesn't really serve too much melodic purpose. Good for showing off, though.
