The Mig module series is new line of vacuum tube based eurorack synthesizer modules.
 
Collaboratively brought to life by Catalyst Audio and Electroserf - the MiG modules utilize obsolete cold war era Soviet vacuum tubes, originally fabricated for use in Mikoyan-Guyverich (MiG) fighter jets.
 
The Mig series was designed from the ground up around the 1j24b vacuum tube, and these tubes are utilized for the core functionality of each module, with additional analog circuitry utilized for buffering and processing as needed. These modules are NOT the same circuits you have seen before with a tube stage tacked on to the output.
