The BF-22 VCF is a dual Hi/Low-pass filter inspired by the Sallen-Key filter from the early MS-20.
DIY version of the Befaco-BF-22-Sallen-Key-Filter.
The kit includes all the components needed to assemble this module, as well as the panel, the screws and the power supply.
However, you must be equipped with at least one soldering iron and tin.
