Is there anybody has any idea which pedals might be used for this song? I looked up on comments but there is no answer at all.
From this video seems like the sound is coming from an Fender Hot Rod Deluxe, which is a tube amplifier. This is what is making this kind of "vintage" sound.
From here you can have a glance on the pedals, seems there is at least a Big Muff Pi and a Boss Overdrive plus maybe a Mooer Octave and an unidentified pedal… It is likely that not all of them (maybe none) are used in the song you linked ;).
Hope it helps!
