What the Hell is He USING?!: '84 Sheepdog - As Cities Burn

[bergie]

Oye Gents,

I'm trying to decipher what exactly is going on with this amazing, crazy song. Of course talkin about the fuzzy, filtery, synthy part in the very beginning throughout the song.

What pedals do you think could replicate this sound? Is it even bass?

I love As Cities Burn! I'd think a fuzz pedal + an envelope filter?
