Frequency wise it's usually around
8-10 khz for the air 4-6 khz for the bite area, usually 1.5 khz for the in your face effect, 400hz for the note of the guitar, and around 70-100 hz to pick out the weight of the cab.The boost amount just depends on what has been recorded, just turn it till it sounds good. This method has worked on many albums i have worked on including Heartwork Carcass, Burn my eyes Machine Head, Chimaira self titled, Bullet for my valentine, The Poison.
И да, все это бусты) никаких катов)
