How to get that huge guitar tone (part 1\3)

The guitars sound like shit. Title of video should be: "How to get that fizz-city guitar tone".
 
I wouldn't go as far as saying it's shit (I've heard much worse), but I agree there is room for improvement. There is something wrong above 2k in your tone, and you go and boost it even more at some point.

I think most amp sims generate some garbage between 2k and 6k, so there is usually a lot of cleaning to do there.
