Which microphone should you use for acoustic guitar? For recording, a condenser microphone is usually the best choice, often a small-diaphragm model, because it captures the bright attack and detail of an acoustic guitar well. A dynamic microphone such as the Shure SM57 is sturdier and less sensitive to background noise, which makes it especially handy on stage. Place the microphone about 12 inches (30 cm) away, aimed at the spot where the neck meets the body.
Why Your Microphone Choice Matters So Much
When you record acoustic guitar, choosing the right microphone is crucial. After all, the microphone is the instrument that captures the sound of your guitar and carries it to the recording. A good microphone can capture the nuances and rich tone of your guitar perfectly, while a less suitable one can mask those qualities.
It is important to understand that not all microphones are equal; they have different characteristics that affect the final sound quality. When recording an acoustic guitar, you want the microphone to capture the full range of the sound, from the high notes to the low bass tones. This means you need to look at the frequency response and the sensitivity of the microphone. If you first want to know what else you need, read how to record your guitar playing at home.
A microphone that is not well matched to the frequencies of an acoustic guitar can result in a recording that sounds flat or uninspired. That is why it is essential to invest time in choosing the right microphone, so you can get the best out of your recordings.

Condenser vs. Dynamic Microphones: What Is the Difference?
When choosing a microphone for recording acoustic guitar, you will often come across the terms “condenser” and “dynamic”. These two types of microphones each have their own characteristics and uses. Condenser microphones are generally more sensitive and have a wider frequency response than dynamic microphones.
This makes them especially suited to capturing the subtle nuances and detail of an acoustic guitar. They are often preferred for studio recordings, because they can capture a brighter and more detailed sound. Dynamic microphones, on the other hand, are sturdier and better able to handle high sound pressure levels. You can read how this works in a real studio in playing guitar in a recording studio.
This makes them ideal for live performances or situations where you have less control over the environment. Although they may not offer the same clarity as condenser microphones, they can still produce a warm, full sound, especially when they are positioned well. It is important to consider the context in which you are recording, so you can decide which type of microphone best fits your needs.
Small Diaphragm, Large Diaphragm and Phantom Power
Condenser microphones come in two kinds. A small-diaphragm microphone, such as the Neumann KM 184 or the Shure SM81, captures fast attacks and high notes accurately and naturally, which is why it is widely used for acoustic guitar. A large-diaphragm microphone, such as the AKG C414, Audio-Technica AT4050 or Rode NT1-A, often sounds a bit fuller and warmer and also suits vocals. If you want to record both vocals and guitar with one microphone, a large-diaphragm model is a practical choice.
A condenser microphone needs phantom power (48 volts). Most audio interfaces with an XLR input supply it with one button. You can read how to connect such an interface in using an audio interface with your guitar. A USB microphone plugs straight into your computer. That is simple, but you have less choice and fewer options for expanding later.
Popular Microphones for Recording Acoustic Guitar
Several microphones are popular with musicians and sound engineers for recording acoustic guitar. One of the most highly regarded models is the Neumann KM 184, a condenser microphone known for its excellent sound quality and precision. This microphone captures the sound of the guitar in a natural way and is well suited to both studio and live recordings.
Another popular choice is the Shure SM57, a dynamic microphone often used on various instruments, including acoustic guitars. Although this microphone is not as sensitive as a condenser, it offers sturdy construction and excellent sound reproduction, which makes it ideal for live performances. There are also models such as the Rode NT1-A, known for its low noise and clear sound, which makes it an excellent choice for studio recordings.

How Do You Choose the Best Microphone for Your Acoustic Guitar?
When choosing the best microphone for your acoustic guitar, it is important to consider several factors. First, think about the kind of music you play and how you want your guitar to sound in the recording. If you play fingerstyle, for example, and put a lot of emphasis on the subtleties of your playing, a condenser microphone may be a better fit. If you play percussively like Tommy Emmanuel, also read how to learn fingerstyle in his style.
If you mostly strum hard, a dynamic microphone can also work well, although it captures less detail. It is also important to look at your budget and where you will use the microphone. If you mainly record at home, you can invest in a high-quality condenser microphone.
But if you often perform live, a sturdy dynamic microphone may be a better choice. Don’t forget to experiment with different microphones and setups to find out what works best for your specific situation. You can read more about that in tips for performing with acoustic guitar.
Tips for Setting Up the Microphone for Acoustic Guitar Recordings
How you place your microphone can have a significant impact on the quality of your recording. A common technique is to place the microphone about 12 inches (30 cm) from the guitar, aimed at the body. This helps capture a balanced sound without unwanted resonances. If you aim it right at the sound hole, the recording often sounds boomy. A good starting point is the spot where the neck meets the body, around the 12th to 14th fret.
It can also be useful to experiment with different angles and distances to see how they affect the sound. Another important tip is to take the environment you record in into account. Try to minimize background noise and choose a room with good acoustics. If your room sounds hollow or echoey, take a look at tips for playing guitar in a small room.
Using sound-absorbing materials can help reduce unwanted echoes and reverb, so your recording sounds cleaner and more professional. Don’t forget that even small adjustments to the position of the microphone or to the room itself can make a big difference to the end result.

The Importance of Acoustics and Background Noise When Choosing a Microphone
The acoustics of the room you record in play a crucial role in the quality of your recording. A room with hard surfaces can lead to unwanted reflections and echoes, which results in a less clear recording. It is therefore advisable to choose a room with soft materials such as carpets, curtains or foam panels that absorb sound.
This helps capture a cleaner and more balanced sound. You also need to take background noise into account. Sounds from outside, such as traffic or people talking, can be distracting while you record.
Try to minimize these sounds as much as possible, for example by recording at different times of day or by using soundproofing. A quiet environment makes sure your acoustic guitar recordings sound clear and professional. You will find more solutions in tips for recording guitar without noise.
Alternative Recording Methods for Acoustic Guitar
Besides traditional microphone setups, there are alternative methods for recording acoustic guitar that are interesting to explore. A popular technique is to use contact microphones or piezo elements attached directly to the guitar. These pick up the vibrations of the wood itself, which can result in a unique tone that is hard to get with traditional microphones. If you have an electro-acoustic guitar, you can also record the built-in pickup through the instrument input of your audio interface.
Another interesting option is to use digital recording equipment such as audio interfaces or mobile recorders designed specifically for musicians. These devices often offer built-in effects and sound-editing options, which gives you more control over your recordings. By trying different techniques and equipment, you can discover new sounds and develop your musical creativity further.
The Importance of Good Cables and Preamps for Acoustic Guitar Recordings
When recording acoustic guitar, it is important to focus not only on the microphone itself but also on other components such as cables and preamps. Good cables make sure there is no signal loss or noise during recording, which is essential for clear sound reproduction. Cheap cables can cause interference and lead to unwanted noises in your recording.
The preamp also plays an important role in the recording process. A good preamp amplifies the signal from the microphone without loss of quality, so you get a cleaner and more professional sound. Investing in high-quality cables and preamps can therefore bring a significant improvement to your acoustic guitar recordings, which ultimately contributes to a better end result.
By paying attention to every aspect of the recording process, you can make sure your music sounds as good as possible.
