Slash got it right. I'll agree with IM4Tone that a single line rendition lacks a bit - after all chords are possible with a guitar. Thanks for pointing out the hat removal for the anthem angle - that makes sense. For me, the reasons I dislike the Santana version are more about the tempo, the spastic phrasing, and the overall odd approach than the tone. The tone definitely was not close to his usual standard either, and I don't think you can blame that entirely on the venue (as Slash also demonstrated).
