https://www.youtube.com/watch?v=x-OYU5w3dAA Right at the very beginning. Sounds like some power chords but it sounds like very low and very high notes are being hit at the same time and I can't place it with my ear enough to figure out exactly how it's being done. I know this is some basic stuff but I figured I'd ask in order to get an informed answer rather than guess all day. Any one have any idea? One guitar or two? What chord if any is being played or anything like that? Any info would be appreciated. Thanks.
