Gear and choices for different tracks

So hopefully this doesn’t feel too much of an open question.

I know there aren’t any right answers.

1.

But what is your approach to choosing compressor, EQ and others effects on tracks?

Do you tend to go for the same gear on certain instruments or do you switch up things from time to time?

2.

How do you like to layer or EQ sounds like bass, kick, snare, guitar and vocals?

Is it totally different each time or is there ways you found that of works more often than not.

For example the foo fighters where there seem to be so many guitars, busy drumming, loud vocals and even a bass that get its fair share of space.

Is it possible to get a glimpse inside of how you’re thinking when you make the decisions of what goes where;)
