Just buy it ... I cannot mix without it ... vocals, drums, guitars, keys ... you name it - it goes everywhere. Track inserts, parallel, buses, main mix ... cannot go wrong with this one for every style of music. Extremely musical compression. Add Neve EQ's LA2A, 1176, distressor. DBX160, Fairchild, Manley varimu, and Pultecs and if your mix doesn't sound up to professional standards, it's definitely you, not the tools ...
