Blokañ is built around on the classic diode ring, where the diodes are tube based. The module uses a built in carrier signal (saw wave) VCO (V/Oct) with is own output. In use the tube ring mod acts like a real ringmod with the benefit of sounding different from others due to the tubes usage, but it can be also on the noisy side, as the diodes in the tube can’t be matched, and it can leak a little the carrier wave, "it's not a bug, it's a feature “.
