"Analog Obsession released the Rare “BPB Edition” passive equalizer plugin with a new oversampling feature and macOS Big Sur compatibility.

Rare is a passive equalizer plugin inspired by the classic Pultec hardware. Unlike the hardware, though, Analog Obsession’s design features an optional pre-EQ gain stage. You can use it to saturate the signal before it hits the EQ circuit."
