In the case of a solid body electric violin, the strings will vibrate. These vibrations will create an electric signal that is then sent to an amplifier, where the sound quality of the electric violin will be affected by the type of bridge and the number of sensors it possesses.
Classical violins have 4 strings: D, G, A, and E. An electric one can have more than 4, which gives the instrument a higher sound.
Although they vary based on the model, acoustic violins will have a standard size and design. And every detail that characterizes these masterpieces you can find there: f-holes, the ribs, the tailpiece, the soundboard, etc.
On the other hand, electric violins can look very daring and different. Those main things that make an acoustic violin can be removed from the electric instrument without affecting the sound. Respecting the basic violin format with elements such as the neck and the fingerboard, the electric violin can have any type of design, color, or even materials.
Each violin has its own particular characteristics, and we defend the acoustic instrument for a personal reason. However, no matter your choice, the main thing here is that you enjoy your violin as much as possible, it should be something that you love doing. Some violinists will have both, especially professional ones, to choose from depending on the situation.
Electric violins are excellent, just like any other instrument, but our point here is only to present you with both options, how each works, and why we love more the acoustic one.
