This plugin is a painstaking recreation of the coveted UnFairchild 670M mkII Vari-Mu Compressor. A design and development collaboration between MIXLAND and Eric Valentine, it is a process that starts with testing and measuring then, listening and experimenting and tweaking and refining over and over and over for over 6 months. The result is a plugin that unquestionably captures the unique vibe and character of the hardware. Now we can all enjoy the magic and mojo of the classic UnFairchild sound in plugin form. The features and controls for the UnFairchild 670M II plugin are the same as the hardware, with a few additions. We added an Output Level Control, Wet/Dry Mix control, and an Overall THD control. The Overall THD (Total Harmonic Distortion) control allows you to increase or decrease the amount of UnFairchild style THD character.”
