A channel comp in the spirit of a G series but with a gob more features that take it into other styles of cmpression. I REALLY like this compressor and use it frequently anywhere I need VCA style compression. The continuously variable knee knob and RMS control are great for changing the squash on those below threshold notes and the tube knob seems to take her from crisp SSL into a more vintage territorywhere there's harmonics being added when the compressor is working but you still have that dbx/ssl character to the grab and squish.... I really like this thing and tip my hat to MSG again. Very underrated company.
