An interesting device using the sound from a gloomy drone to the sounds of dolphins. The device is filled with various sound effects and sounds.
Toggle switches of the Soviet military acceptance, will last a long time!
Also USSR transistors and microcircuits are a powerful base for a unique sound.

Another photo of this instrument.

Strangely, the auction appears to have been canceled. But I am intrigued by the idea of new instruments based on Soviet components, so we will see if it ever returns.
