wow!! A lot of replies!! Thanks you guys - just gotta wait to get my tracks back from the rec studio then I can begin playing around with your suggestions!!
this badboy is what I use for whole mixes and it helps making it louder and touching up or mastering if you would. It works great for instruments but you can also use the regular Sonitus compressor. I just like this one because it doesn't have the pump effect. After using this and then a limiter, oh man...your mix is LOUD.
