Analog Sweden swEnigiser Proto VCF/A

VCF+VCA from the ENIGISER

Background

The VCF/A is based on one of the earliest prototypes of the original Orgon System Enigiser, which was repaired for Anthony Linell of Northern Electronics. To our surprise it was built entirely on protoboards and using other components than was used in the production Enigisers. We really liked what we heard and the result is what you now have, adapted for eurorack.

The filter is built on 4x 6db cells in series with selectable inputs (A,BC) and outputs (1-4).
