Small Tube VCA/Distortion Modules

There seem to be more and more folks making modules with small tubes these days. I have a few of them, and figured I'd do a comparison. These are all "distortion" modules in one sense or another. Some are VCAs, some are filters, and some are just tube-y grimy-ness. I've also thrown in an intro to the cDVCA, a new kind of VCA that is also a specialist at distortion. It doesn't have a tube, so it gets a solo spot at the end. Source audio is the saw out of an Acid Rain Chainsaw. Envelope from Zadar.
