I think this thing is supposed to be a GML emulation. It looks right. Massenberg invented parametric. There's a real sound to a GML rack.... this isn't really the same to my ear, the pahse shift is different. ut it sounds good, and is great to sue when don't want a graphical representation fow hat you're doing to fuck with your ears. Soemtimes too miuch looking gives you 'correct' results but not creative results.... surgical EQ can go beyond repair work and that's where stuff like this shines. Try using fab fitler without focusing on the spectrum analyzer and letting that make decisions for you! Apart from gain metering when needed I just don't like seeing the music.
