Description :
This plug-in is a painstaking recreation of the long-awaited Unfairchild 670M Mkii Vari-Mu audio compressor with improved sound.
Developed in collaboration with MIXLAND and Eric Valentine, the project involves a process
that begins with testing and measurements, then listening and experimenting, and then tweaking and refining over a period of over six months. The result is a plug-in that undoubtedly
captures the unique atmosphere and character of the hardware. Now we can all enjoy the magic of the classic Unfairchild sound in plug-in form.
The functions and controls for the UnFairchild 670M II module are the same as the hardware, with a few additions.
We’ve added a power level control, wet/dry mix control, and a master THD control.
The Total Harmonic Distortion control allows you to increase or decrease the amount of UnFairchild-style distortion.
It’s possible
Check out how closely the plugin matches your hardware with this amazing drum compression system!
