Electromechanical musical instruments - a subclass of musical instruments of the electrophone class. The sound of an electromechanical instrument, excited by a natural sounding body (string, metal plate, pillar of air, etc.), is converted into an electrical signal and transmitted to the ULF using an electric pickup, a breath controller (on wind instruments), etc. In the usual case, before amplification, the “acoustic” sound is subjected to additional processing in the electronic unit of effects.

Principle of Operation
In electromechanical musical instruments, sound is created by converting mechanical motion (for example, vibrations of strings, tuning forks or gears) into an electrical sound signal using various sensors, such as pickups [1] . An audio signal is supplied to the amplifier and reproduced using the speaker .
For example, in an electric guitar, sound occurs when you hit a string, but the guitar’s own sound is not used. Oscillations of the string cause a signal to appear in the pickup, after which the signal is processed by various sound effects (such as distortion , fuzz ), which significantly changes the original timbre (color) of the sound.
