I actually think Varg Vikernes is highly underrated as a guitar player. Even without great complexity there's always something special in his guitars. Of course he doesn't play live, so maybe he's not as good live as he is in the studio.
On another note: Matt Wilcock, ex-Akercocke, is a mean fucking guitarist. His technique and chops live are seriously good.
The Green Day guitarist (Billy Joe Armstrong, I think?) can apparently shred pretty good but I've never heard or seen it - might just be a rumour.
Ralph Santolla (Obituary, Death, Deicide, Iced Earth, etc).
I hate that dude.
Add the fact that Deicide and Obituary blow nuts.
Anyone who thinks Ralph Santolla layering power metal solos over some crappy worn out/washed out death metal bands is good sucks at listening too Death Metal.
It's not, it's an opinion; learn to discern between them please.
