One of the most useful plugins I have, even over paid for ones. You have to be a bit careful as you can kill a mix with this, but used thoughtfully you can get near pro results. Each individual element is a great tool in itself. Don't expect an instant result with this. You need to get a feel for each element to get the best results. I don't even recommend using the presets. Just feel your way. Maybe start with getting the meters to peak around 2 DB and see where that takes you.
