Ableton Live Saturator Plugin

Virtual Riot use this plugin in this video :D

"Ableton Saturator is next and I probably put this on 99% of my vocals to varying degrees and I literally use the default preset but just dial in the drive to different amounts. (...) And as you're about to hear, this just warms things up a little bit. I feel like it slightly compresses things as well and just kinda glues it a little."
