BH plays EVERY style with ease. Listen to acoustic shards and be blown away and that's a shitty acoustic album lol.
BH could play Slashs style and his own easily, Where as Slash could never hope to play BH's style.
Put BH on the spot to do any Slash solo and it would be done with ease, Same as Bumblefoot, Slash would struggle and die trying to pull of BH's Jordan or Cactus by BBF.
I love Slash i love what he did with GNR and Contraband and even a couple of the Libertad songs but there's no shame in stating the reality that he's not a superior gutarist to BBF and BH's talents.
I think it's wrong to say that a musician (whoever he is) is superior to another.
I only see different musicians, and I like music for what it is, and not what it could be. I love Slash for what he plays and not what he could play. And I don't dislike him for what he couldn't play, that doesn't make sense.
It's not just like building a car, it's all about music and feelings and not about statistics.
Just an opinion.
I like Buckethead too. But not as much as Slash, the only judges are my ears and my feelings.
