This plugin is sort of a niche product, but could be the best sounding plugin available as far as hardware modelling. Its similar to a convolution reverb, but uses impulse responses from all sorts of hardware. The demos I've heard are quite impressive.
This is a new set of compressors I've made for Nebula. Nebula compressors have had a reputation for not really being too reliable for their compression abilities, and many people just use them for their tone and use a separate VST for compression. I think this set of comps should change that. They are based on very transparent hardware but the results still sound like analog compression. You can even limit with some of them and it's still fairly transparent, but smooth.
