Полная импровизация. И давняя идея совместить радио с эстетикой дрон-звучания и другими нойз-структурами. После долгих мытарств получилось уже что-то интересное. Можно развивать эти идеи дальше).

Complete improvisation. And an old idea to combine radio with the aesthetics of drone sound and other noise structures. After long ordeals, something interesting has already been obtained. These ideas can be developed further)."

"Sound effect - sound modulator. A. Chervonsky.
In the video, first the sound from the electric guitar, from 2:45 with the voice, and from 4:12 from the audio player, the voice and the song.
Description from the magazine: "the described device makes it possible to modulate the amplitude and phase of the EMI signal with the audio frequency voltage from the auxiliary generator. The sharp specificity of the resulting musical effect (there is no established name for it) significantly limits its use, but in a number of cases of pop practice it can be quite justified. The frequency of the auxiliary generator can be changed during the game, introducing new colors into the sound of the instrument. In addition, the device has a vibrato generator, which additionally modulates the amplitude of the generator signal, which, in turn, leads to a timbre vibrato of the sound at the EMI output. The device has been tested in operation together with an electric guitar, but it is possible that good results can be obtained with other EMI."

(my addition - added a microphone amplifier to the circuit (it also came in handy for amplifying the guitar). The low-frequency generator (vibrato) is of course already outdated and has a small range. I increased the value of resistor R25 by 47-50 kilo-ohms, otherwise vibrato would not work. And I decided to add a variable resistor of 1 mega-ohm, after R12, to adjust the intensity of the effect. Although this does not give much)."
