That guy is a HORRIBLE teacher. "what is x? It's y" an equally obscure term to a LAY PERSON. (I have 2 graphic EQ's, one 32 and one 64 (stereo))). His diagram explanation are retarded (teaching tool). There are SO many holes (info missing) in what he is trying to explain (not just what terms mean). The guy also seems a little drunk (BAD sign), AND seems to forget what he's talking about midstream. Editing is horrible too. This guy is a dumbass who probably knows something about what he's doing (running live sound), but NOT how to TEACH it (LACK of understanding of the concepts). thinks too much of himself (seems smug). IT seems like he didn't prepare beforehand much at all. He should be shot.
