Its very solidly made, feels quality all over.
I'm not yet using it with mics, I'm using it as HW insert in DAW.
Its really nice for gently taming some nasty high end, and for getting peaks under control. The different options are all very subtle to my ears apart from the tone +6db button which is obvious.
It does have a good range of distortion / saturation but I did expect a little more given the 'beast' in the model name. Anyway it gets plenty of use and I'm glad I have it.
