Freeware - Variety of Sound FlavourMTC Mixbus Tone Control VST Plugin

https://varietyofsound.wordpress.com/2022/05/09/flavourmtc-mixbus-tone-control-released/

FlavourMTC follows classic “passive” equalizer designs where the EQ circuits itself are not able to amplify signals but a dedicated amplifier stage takes care of it. Those EQ designs are well known for allowing very transparent frequency changes while their amplifier designs do add some icing on the cake quite often.
