Hey thanks for the compliment bro...keke yeah both of us used the 7th heaven!
The heavy rhythm guitar parts....I played layered them in both standard E and Drop D tuning. Kinda contributed to the whole "wall of sound" guitar thing.
The clean palm-muted parts were recorded with the 7th heaven on "clean" aka volume knob on guitar rolled down for that slight breakup and "grit" and Goose's custom fuzz also made its debut on the lead parts at the beginning and middle!
