You want a “conservative” low end where nothing sticks out too much or is lost completely. Focus on the relationship between the kick and the bass.In a melodic bass line, all the notes should roughly be at the same volume.A standard iici should have some sub and some punch.Put your head right up against the wall. That’s what too much sub sounds like. Move back into the room. Where do you still hear the sub, but the punch comes back it?Focus on the sub in your stomach and the punch in your chest. You want to feel both at equal strength.It shouldn’t be too much fun, or too boring to listen to!
