I don't find anything too terrible about the playing on that track. It's obviously been "doctored" to sound bad on Youtube, probably as a swipe at MA, which would certainly be in keeping with the Van Halen brothers' previous behavior. I have a studio reference audio interface and monitors on my internet computer, and there is almost no low end there, just a farty, clacky, SVT tone that has had all the life compressed out of it by something of the 1176-ilk. The fret and string noise are horribly exaggerated, while the "meat" of the tone is missing completely and there is virtually no dynamic movement at all. MA isn't my favorite player by any stretch, but old Van Halen albums don't have that bass sound either.
