An electric-acoustic guitar is an instrument that combines the traditional acoustic guitar sound with electrical components. It uses a piezo pickup, which is installed under the bridge saddle of the guitar and transmits string vibrations to an amplifier. The piezo pickup senses vibrations from the strings and sends them to an onboard preamplifier that can be used to adjust volume or tone. This amplified signal can then be sent through speakers or headphones for a louder sound. With the use of additional pickups, it is also possible to blend different sounds in order to create more complex tones and textures.

Anatomy of an electric-acoustic guitar
Electric-acoustic guitars are a hybrid of electric and acoustic guitar components. They have an internal microphone, preamp and pickup to capture the sound from the strings that can be amplified through an external speaker system or headphones. As well as these electronic components, they also feature standard acoustic features such as a fretboard, bridge, nut and tuners. By combining all these elements together, electric-acoustic guitars offer players the best of both worlds – great sound projection when plugged in to an amplifier or mixer, but also enough volume for unplugged playing.
To understand how this works let’s look at each component individually. We will start with the pickups; on most electric-acoustic guitars you will find two magnetic humbucker pickups which pick up vibrations from the steel strings and convert them into electrical signals which can then be amplified by an amp. The preamp is designed to control the output level of these signals before they reach the amplifier or recording device – it allows you to boost bass tones or cut treble tones depending on your preference. The internal microphone is usually placed just under the strings and captures their vibration like a normal acoustic guitar would – this helps create a more ‘organic’ sound when using headphones or amplifiers without any additional effects applied.
Finally there are other traditional elements found on many modern electric-acoustic guitars including bridges and nuts made from metal or bone, thick steel frets for increased sustain and accurate intonation along with precision tuning machines for optimum tuning stability. All these pieces work together to produce a unique hybrid tone suitable for almost any style of music.
How does the pickup system work?
An electric-acoustic guitar is equipped with a pickup system that produces the sound when a string vibrates. The pickups are basically small magnetically charged coils of wire wrapped around an iron bar, also known as pole pieces. When strings on the guitar move and create vibrations, it disturbs the magnetic field and causes an electric current to be produced in the coil of wire. This electric current is then transferred to an amplifier or mixer so that it can be heard.
The type of pickup used depends upon the genre of music being played by the musician; different genres require different sounds from the instrument. Single coil pickups are usually found on vintage guitars and produce a bright, cutting tone which works well for playing rock, country, blues and other popular styles of music. On modern guitars dual-coil pickups are often used; these have two coils wired together for increased output but can sometimes suffer from noise interference if too close to electrical sources like TVs or computers.
Active pickups offer even more control over their sound than passive pickups due to their built-in preamps and EQ controls which allow them to shape their own sound rather than relying solely on external equipment such as amplifiers or mixers. These types of pickups are perfect for players who want ultimate control over their guitar’s tone without having to rely on expensive external gear – they offer clear tones that can cut through any mix without overpowering everything else in the room.
Understanding the preamp and EQ controls
Electric-acoustic guitars come with their own preamps and equalizers, providing the musician with full control over the instrument’s sound. This can be done by making subtle adjustments to the individual strings or to create a more customized sound for specific musical styles.
The most common type of preamp is a six-band equalizer, which allows you to boost or cut each string independently. It also provides three separate controls that affect the entire guitar at once: bass, mid-range and treble. The user can adjust these parameters according to their personal preference in order to achieve their desired tone. Some preamps provide additional features such as an auxiliary input or gain control, allowing players to tailor their sound even further.
Equalization is a crucial component of electric-acoustic guitars because it allows musicians to shape their tone without changing pickups or amplifiers. Different frequencies will emphasize certain characteristics in the instrument’s sound; so depending on what genre of music you are playing and your desired effect, adjusting the EQ settings may be necessary for achieving that particular sound. By manipulating the knobs on your guitar’s preamp and EQ controls, you can find just about any kind of tone imaginable from an acoustic-electric guitar.
Differences between passive and active pickups
When it comes to electric-acoustic guitars, there are two types of pickups – passive and active. Passive pickups detect vibrations in the strings that create a signal and then amplify this natural sound. This is why they don’t require any additional wiring or electronics to function properly, making them the most common choice for those looking for an easy installation.
Active pickups on the other hand are powered by a battery which gives them more power and clarity than their passive counterparts. They have stronger magnets inside the pickup which helps them detect even the smallest of string vibrations resulting in improved tone quality. While this makes them louder than passive pickups, it also requires additional wiring and components as well as extra maintenance from time to time.
The type of pickup you choose will depend largely on your playing style and desired sound but regardless of what you decide, it’s important to make sure that you get quality hardware that will help you produce great music at all times.
Tips for maintaining your electric-acoustic guitar
Electric-acoustic guitars are becoming increasingly popular in the music industry, and they come with a unique set of maintenance requirements. To ensure your electric-acoustic guitar continues to perform optimally, it is important that you follow these steps for proper upkeep:
First, keep your strings in tune by using a digital tuner or an app on your smartphone. Your guitar strings should be checked before each practice session and adjusted as needed. It’s also important to clean off any dust from the strings after each use. This will help keep them sounding crisp and clear longer.
Second, inspect the bridge regularly for signs of wear or damage that can affect playability. Make sure all screws are properly tightened so that intonation stays true. Also check the nut slots for debris that may have accumulated there over time; remove this gently with a soft brush or cloth if necessary.
If you plan on leaving your instrument idle for an extended period of time (e.g. while touring), consider storing it in its case inside a temperature-controlled room such as an air-conditioned home or office space. This will protect it from extreme temperatures which could cause warping or other structural damage over time.
