Ok here's my advice.
Guitars = Cut or boost the lows if its sounds good to your ears, or maybe cut or boost the mids if it sounds good, or the highs if that sounds good. Or maybe a combination if it if it sounds good. The cuts/boost should be somewhere between 20hz and 40khz. You might want to use some compression, but then equally you might not.
Bass = Cut or boost the lows if its sounds good to your ears, or maybe cut or boost the mids if it sounds good, or the highs if that sounds good. Or maybe a combination if it if it sounds good. The cuts/boost should be somewhere between 20hz and 40khz. You might want to use some compression, but then equally you might not.
Drums = For each piece, cut or boost the lows if its sounds good to your ears, or maybe cut or boost the mids if it sounds good, or the highs if that sounds good. Or maybe a combination if it if it sounds good. The cuts/vocals should be somewhere between 20hz and 40khz. You might want to use some compression, but then equally you might not.
Vocals = Cut or boost the lows if its sounds good to your ears, or maybe cut or boost the mids if it sounds good, or the highs if that sounds good. Or maybe a combination if it if it sounds good. The cuts/vocals should be somewhere between 20hz and 40khz. You might want to use some compression, but then equally you might not.
I don't understand? Death music? Like for funerals? Or when someone dies in a film? Or are you recording people dying? I'm confused. What are you trying to EQ? And why? And when? And in what capacity? And what for? And a whole bunch of other questions that equate to "I don't have a clue what you are talking about"
