Thank you guys - and @miroslav: you're totally right, training your earing is very important. Just wanted to get some tips/informations whether there are some good plugins to improve my mixes.
The problem with the NBT2020 is the knobs are not labeled and when you try to make it give you the "Next Big Thing" it's hard to tell which is the "Sucks" and which is the "Awesome" knob.
I usually get the wrong one.
Not making fun of the OP, just having a little myself.
That's just it man. Your ears are what will tell you what sounds good.
Most modern DAW's already have spectrum anal-yzers built into them.
I would look into updating your DAW if it doesn't have something like that in it already...
