What is an electric acoustic guitar?

An electric acoustic guitar, also known as an electro-acoustic guitar or a semi-acoustic guitar, is a type of guitar that combines elements of both acoustic and electric guitars. It has a hollow or semi-hollow body like an acoustic guitar, which helps produce a natural acoustic sound. However, it also has built-in electronic pickups and preamp systems that allow it to be amplified, making it suitable for live performances or recording sessions.

Here are some key points to know about electric acoustic guitars:

1. Body Design: Electric acoustic guitars typically have a similar body shape and size to acoustic guitars, including dreadnought, concert, or jumbo styles. The body is usually made of wood, such as spruce, mahogany, or maple, which contributes to its resonance and tone.

2. Sound Projection: Like acoustic guitars, electric acoustics produce sound by the vibration of the strings resonating through the body. However, the built-in preamp and pickups capture these vibrations and convert them into an electrical signal that can be amplified through an external sound system or amplifier. This allows the guitar sound to be projected loudly in live performances or recordings.

3. Controls and Electronics: Electric acoustic guitars feature built-in controls on the body, such as volume and tone knobs, that allow the guitarist to adjust the amplified sound. They also have an output jack where the guitar can be connected to an amplifier or sound system. Some models may include additional features like onboard tuners, EQ controls, or microphone blending options.

4. Versatility: Electric acoustics offer versatility to guitarists as they can switch between unplugged acoustic playing or amplified performances with ease. They can be played through acoustic guitar amplifiers, PA systems, or any standard guitar amplifier, depending on the desired sound.

5. String Types: Electric acoustics can be fitted with various string types, including steel-string or nylon-string options. Steel-string electric acoustics are more common and are suitable for a wide range of genres like folk, rock, pop, and country. Nylon-string electric acoustics are often used in classical or flamenco styles.

6. Maintenance and Care: Similar to acoustic guitars, electric acoustics require regular maintenance for optimal performance. This includes string changes, occasional truss rod adjustments, and keeping the instrument clean and properly humidified. The electronics and battery of the preamp also need to be checked and replaced if needed.

Overall, electric acoustic guitars offer the best of both worlds by blending the acoustic warmth and tonal character with the amplification capabilities of an electric guitar. They are widely used by musicians, both in the studio and on stage, for their versatility, convenience, and ability to deliver a rich, amplified sound without sacrificing the acoustic qualities.
