Fabfilter have really set the standard that others should be judged by with these excellent plugins.
The Fabfilter plugins have excellent user interfaces and sound absolutely amazing. They are also loaded with innovative features you won't find elsewhere. They really make mixing "in the box" both easier and faster than ever before. The eq is perhaps the biggest star of the collection but they are all great and have quickly become my most used plugins by far. I can't praise them enough. Highly recommended!
