Randy Rhoads Isolated guitar tracks

Here's an excerpt from the article:

How was the “Crazy Train” solo recorded to get such a clear, piercing sound?

This is one of them that was triple tracked. If you listen to that track real close, you’ll hear there’s one main guitar around the center, as I remember, and there are two other guitars playing exactly the same thing, panned to the left and right, but back somewhat. And actually what happens is you don’t hear them – you just hear it as one guitar. He was the best guy at overdubbing solos and tracking them that I’ve ever seen. I mean, he used to blow me away. So on a lot of those things, when you hear a guitar that really comes out, that’s because there are three of them there. And it’s not like an ADT – he’s actually playing them three times, which means you get a very stable image. It really does sit there, rather than shift left or right, depending on where the delay is. That’s really the reason for that. Plus it’s a Charvel – they have an extraordinary top end. (I'm pretty sure that he's talking about the Polka dot Sandoval V...because he refers to the Charvel with polka dots in another part of the interview)
