Erica Synths Black Polivoks VCF is one of the most authentic sounding emulations of the famous Russian synth the Formanta Radio Factory Polivoks.

The original Russian ICs K140UD12 are used in the sound circuit but with upgrades; it has independently buffered inputs, extended Cutoff knob, eliminated clicks when switching filter modes and output stage added to eliminate signal inversion. The result is a much punchier bass sound and very smooth controls.

Note: This is a used item, and while it is guaranteed to be fully functional it is almost sure to also contain "rack rash" on the mounting holes and have some minor scratches on the panel from use. It will include a ribbon cable, m3 screws, and a box, but not the original box.
