I am pretty close with my chain. Seems like HPF rolls off around 500 down to 250 ish (deep voice) and is able to bring out the rasp using breathing techniques etc.

Any tips would be recommended on how to get as 'close' to a chain/what may have been used - or perhaps elements of the EQ that I may be unaware of.

Aside from heavy tuning, I've tried many shapes and band pass sends but have still not gotten quite as 'smooth' while being distorted

Thanks guys!
