Excellent sounding compressor, just like a real Neve 33609. The Mk2 has two extra knobs from a standard 33609. One is a switch between a metal knob version for more color and thicker sound and the other is modern version with a cleaner sound. Both cool. Another knob is for wet/dry control, a very useful feature for this compressor. Sad to see this go, but need to downsize. Please give it a good home.
