I’m still exploring but I love frequency 2. While not a plugin, I also love the channel strip for every track.
Least favorite so far would maybe be the compressor. It is not bad at all and does what it needs but kind of meat and potatoes. I prefer my Black Rooster compressor or something with more color than this.
Stock compressor and eqs are great. Fuzz, saturation, reverb, chorus and delays all have me reaching elsewhere though.
