The acoustic guitar provides music through strings that were made from a variety of materials, most notably nylon. Nylon is not only kind to the fingers, but the sound it produces is good and crisp. It is especially important for beginners to use nylon since it is easier to learn. Strings made from steel provide a crisper sound, which is much better on the ears. The downside is that steel strings are harder on the fingers, which tends to put off beginners. Time and practice however will make the effort worth it.

For the benefit of larger audiences the sound of the acoustic guitar can be amplified through a microphone that is situated near the opening of the body of the guitar. If the guitar strings are made from steel, then a pickup from a electric guitar can be used to amplify the sound from the acoustic guitar. These pickups are occasionally referred to as piezoelectric pickups, typically under the bridge of the guitar. Pickups that are electromagnetic in nature operate by converting the vibrations of the strings into an electromagnetic signal that is later amplified. In the case of the acoustic guitar, a hybrid system can be utilized which combines the precise pickup of the electromagnetic components with a microphone that captures the resonance and amplification that the body of the guitar provides.

The hybrid pickup design and overall sound leads most to regard the electric acoustic guitar as an acoustic guitar at heart, despite the electrical amplification. This is resultant of the fact that the magnetic pickups get the sound from the body of the guitar and not the physical movement of the strings. The sound is made from vibrations in the strings, which in turned causes the body to vibrate and the vibrations will transmit to the air within the cavity. The vibration of the air is then picked up and amplified further by the body of the guitar, giving us the sound we hear.

The walls of the guitar body will vibrate and get picked up by the microphone element and the other elements of the electric part of the guitar. This sound will need electrical amplification before it can be heard, but this amplified sound will be very much more faithful to the sounds of the guitar than a purely electrically generated signal.

The primary advantage of the electric acoustic guitar is that the venue can support many more patrons than would be possible with just an acoustic guitar. The performer is given much more flexibility, being able to play acoustically, or add elements that are typical of electric guitar work. External effect pedals can be used to modify the more appreciated acoustic electric sound, leading to a versatility that is not present in either an electric or acoustic setup. The electric acoustic guitar is an example of a guitar that is greater than the sum of its parts, but getting the most from the instrument will require more than the beginner might be able to provide. However, the more experienced guitarist will definitely be able to take the electric acoustic guitar and apply it to creating a much more varied set of music.
