You can see on tabs, muting parts are described as PM on top. It's hard to describe my amp settings since the sound depends very much on guitar itself and also the amp. And I don't really remember the amp settings now on this one video 😅
If I remember correctly your bass should be all the way up, mids should be set to 7/10 and treble needs to be all the way up. Gain is also set to max. It's been quite a while since I covered this song so my settings might be a bit off but I believe that's the amp settings I used when I did it sometime last year.
