The ratio of sequenced tracks vs actual playing is somewhere in the range of 98:100. Guitars just don't sound like that, you'd need a synth for that sound.
And how on earth does a drumkit sound like a TR808. Answer, it doesn't.
As I mentioned in that other thread, these guys are just faking it. Worst part is they're making it too, while the rest of us click on their videos and ensure they get paid irrespective of what they're putting out.
