T-Racks 670 Comp - any good?

It´s no 1176 emulation... It´s a fairchild emulation. It´s pretty good from what I remember, but not for what you want to use it.
Softubes FET is a really good 1176 emulation, but it has a different price tag ;-)

Edit: Aaah ein Münchner! Servus!
 
Yup - that's the Classic Compressor they are selling. While it's a pretty good compressor in it's own rites and probably worth the $10 regardless, the IK 670 Fairchild emulation is a very nice plugin that I'm glad I purchased back in one of the IK group buys on singles.
