Ah, the un- answerable question of the uninitiated. Like you said, it's different for every song to say the least. Also, one must consider the fact that any given verb, comp, whatever is going to sound and behave differently from any other. This question is just impossible. To prove this, check out the presets of some of your plugins. Now, there you go, they're all set up for you. Only... they sound like shit don't they. That's exactly what would happen if we gave you some list of settings. You can use a preset as a starting point, but you'll find out that just spending some time messing around will teach you better than anything else. Especially if you post some of your work in the clinic and ask how to acheive a specific goal. Then some guys can give you some good direction. Have fun.
