Preamp, Compressor and Filter Character
The preamp is based on a 1950s and 1960s measurement instrument that Rogalow Audio adapted into a microphone preamp. In Hainbach's studio it is his main preamp for voice, acoustic mono recordings and synths. AudioThing separated the preamp's overtone-rich gain from the compressor, so you can use each one on its own.
The filters are modeled on passive units that were prized for precision at the time. The developer notes that their peaks ripple across the cutoff frequencies, which becomes most audible when resonance is raised. Frequency markings on the front panel may be inaccurate, so rely on your ears.
