From the developer:
Valve Filter VF-1 is a multimode resonant filter plugin with vintage valve emulation. It has a nice interface with HPF/LPF switch to change the filter mode to Low Pass or High Pass. Bias knob emulates the amount of idle current that the tube draws, slightly changing the behavior of the tube hence the tone.
