Is there such thing as a plug in violin?

Yes, there are violins designed with built-in pickups and electronics that enable them to be amplified without the need for external microphones. These violins utilize piezoelectric or magnetic pickups to convert the instrument's vibrations into electrical signals. They commonly feature controls for volume, tone, and sometimes even equalization. These plug-in violins are suitable for various performances, recording scenarios, and live gigs requiring amplification.
