I think Nuno is incredible and probably one of the best 80s shredder types still around but almost impossible to replace Eddie. He was a brand and magician in the way he kept coming up with the next thing. He might not have created all of them but he certainly developed them.
I mean, the drill in "Poundcake", harmonics starting "Women in Love", dive bomb at the end of "Eruption" that made it sound like the roof was going to come off my house. Those Eddie things. I remember when I saw Eddie playing that Steinberger on "Get Up" and was like WTF? The guy was a genius.
On top of that, he created and played to these amazing, memorable songs. Vai, Satch, Nuno, Slash, etc and so many others are great but Eddie just seemed to represent all of them.
