Abyss Devices makes a couple different tube-based distortions. The Saevitum is bigger, with a resonant LP/HP filter attached, and Saevitus is smaller with no (resonant) filter. Both use 12AX7 tubes and similar amp circuitry, so I was interested to see where their sounds differed or were the same.
Since the Saevitus doesn't have a resonant filter (it has as filter, but it serves mostly as a simple tone control), I focused on the distortion sounds from each module, with my main question being whether the smaller Saevitus was missing anything in that department, or whether it was just as growly as its big brother.
Input audio was a basic saw wave from a Doepfer A-111. Sequenced by
Stochastic IG. Envelope by Zadar.
