Testing A Ring Mod + Sub-Oscillator Circuit

In these quick videos I am testing a DIY Ring Mod + Sub Oscillator circuit through my Tonus VCF (ARP 2600 clone of the 4012 filter). The first video is through a Timefactor Delay. The second video I am punching into freeze mode on the Strymon Big Sky for a colossal wall of sound! The Ring Mod + Sub will become a eurorack module, I will give more info on that soon. Sequenced on Arturia Beatstep Pro. Thanks for watching!
