Metasonix/Serge Random*Source-style 4x4 w/ tube VCO/VCF and VCA

Many users have requested that Metasonix produce tube modules in formats other than Eurorack. We will offer these modules as special limited-production items. They will be based on RK modules except as noted, and use heavy aluminum front panels with engraved and paint-filled lettering.
