Fred isn't thaat good. I mean, I like his playing, but nothing is ridiculous. I've heard great guitar players and I shake my head and say "that's ridiculous," and then I walk off pissed for some reason.
i have heard fred shred some of the most insane riffs ive ever heard when he was messing around at this cmj event a few years ago.
for me though i love the guitar parts he has created. theyre often smart and well crafted. look at a lot of what he did on WYWTB. he has written some of my favorite guitar parts. he has a great understanding of what works in a song guitar wise.
