Projects > IJ Research VCA

Igor’s DIY VCA is a replacement for the hard-to-find DBX202x VCAs found in the original SSL compressors. It’s the same VCA used in Igor’s MixBUZZ1 SSL-type compressor and it can be used in any similar project. The VCA is built around four THAT2181 chips which are widely available.
