Thanks for posting, Donjr. I didn't get into Scorpions when I was a teenager until after Roth left so I don't know much about his work at all. However, an episode of This Metal Show with Roth as a guest I saw recently did make me want to explore his career a bit more.
I'm not a musician so I can't comment on the technical prowess either one of them had, but as a music lover, very few in my opinion have had the ability to play guitar like Gary did. Surely, preferences are just that, but watching his tribute to Jimi just blew me away. For example, Stevie Ray Vaughan's version of "Voodoo Chile/Child" (which is it?!) doesn't even compare to Gary's cover, in my humble option.
