This channel strip is amazing and basically in brand new condition aside from a few fingerprints. Even includes the original box. And it is the Premium version, meaning it has added Lundahl transformers, which makes it more for musical applications rather than voice over work. The de-esser on this thing is nuts, it's not a normal compressor with a side chain for the higher frequency range, and it's apparent in the sound. It's much smoother and less obvious, also hard to overdo it with de-essing. Go watch Colt Capperune's review of this thing, my description doesn't do it justice. Message me with any questions. Thanks!
