An electric guitar is a stringed musical instrument that produces sound using magnetic pickups, which convert string vibrations into electrical signals. These signals are sent to an amplifier, allowing the player to control volume and shape tone using amp settings and effects. Electric guitars are known for their versatility, comfortable playability, and wide range of sounds, from clean and smooth tones to heavy distortion. They are commonly used in genres such as rock, blues, jazz, pop, and metal, making them a popular choice for both beginners and professional musicians.
