The Mig VCO is a Vacuum tube based Oscillator built from obsolete cold war detritus.

3 former soviet vacuum tubes (1960 - 1981) hum and sizzle as electrons are pushed through the various control grids and screens of the 1j24b pentode tubes. The sound is under control - but just barely. Raw electrical aggression that feels both powerful - and like it’s always on the edge of falling apart.
