Kyle does it just before the title of the song shows up at around 04:30 and Jack first says "alriiight!"

He strums up and down, but kinda mutes it at various places, making it "stutter", and it sounds really good. What is it? How do I do it? It's awesome

Yeah, thats exactly what he does, he plays the chords mixed in with mutes. e.g.



|---------------------------------------------------------|
|---------------------------------------------------------|
|--2-----x--2--x--x--2-----x--2----2-2--2-4--4--4-|
|--3-----x--3--x--x--3-----x--3----3-3--3-5--5--5-|
|--3-----x--3--x--x--3-----x--3----3-3--3-5--5--5-|
|--1-----x--1--x--x--1-----x--1----1-1--1-3--3--3-|

I see... what hand does the muting? Fretting or picking?

Thanks

the fretting hand does the mutting, he just switches between the chords and the mutes. I'll try and find a vid on youtube or something that can show u better than i can explain.
