Can Any Mic Be Used With an Acoustic Guitar?

Although you can use any type of mic with your acoustic guitars, experts have decided that some types are more efficient than others. One such type is the small diaphragm condenser mic, which captures all the details with no sound coloration and will ensure high clarity and depth. 

Small diaphragm condenser mics are often used in close-miking the guitar and diminishing the studio’s acoustic influence on the recording. They are great, especially when you are miking other instruments at the same time – such as when in a band. If you want to capture the room ambiance, a large-diaphragm condenser mic will offer you just what you need. 

Can You Really Find a Quality Mic That’s Affordable?

Just like any other product, an expensive mic is not necessarily a good-quality one. In fact, a high-quality mic can also be affordably priced – it all depends on what you need. You need to pay attention to the proximity effect – which means the closer you are, the more emphasis is placed on the lower register. 

This can be handy for some and a deterrent for others, but the muddy effect is not a result of poor quality, but rather improper use of the mic. Some quality, affordable mics have some trade-offs between durability and sound quality, so make sure you choose wisely! 

How to Choose a Mic That'll Work Great With an Acoustic Guitar

Here are some main considerations you should consider when you choose the best mic for your needs:

The Higher the SPL, the Better

An SPL handling capacity means that the mic can handle high sound pressure, so a high SPL is always a good feature to have. This also means that the sounds are noise-free and maintain their stability and integrity. 

Proximity Response

Pay attention to the proximity response, as this will influence quality when performing on stage versus in the studio. This will impact the sound clarity, depending on how far it is placed from your guitar, so you need to establish whether you will be closer or further away from the mic.  


Lastly, choose the best mic for your budget. Of course, unless you want to spend a crazy amount of money, there will be some kind of trade-off between features. The truth is, however, you will never need all the features in one mic, and, even more realistically, no mic has all the features. Therefore, take your time, have a look through the next section below, and decide which one fits your needs the best.

Cautious Considerations to Keep in Mind

Before going for your new acoustic guitar mic, check out the below list of the most important considerations you should keep in mind:


Diaphragm determines the functionality of the mic. Considering that acoustic guitar sounds are quite similar in frequency to vocals, a larger diaphragm condenser might work better than a small one. They are quite versatile, widely available, and we have presented you with some high-quality recommendations, too.

Polar Patterns

Although some mics have three different polar patterns, acoustic guitars, in fact, only need the cardioid. Variety never hurts, but you might find little use to other polar patterns, which are best suited to other instruments. The cardioid is, therefore, the most popular polar pattern. It is simple and effective – all you need for your acoustic guitar!

Reliability and Durability

Although most mics are extremely durable nowadays, it is always a great idea to check the construction materials and its build quality. This is most relevant for frequent gigging musicians or if you travel a lot – this is because you will most likely adjust the mic a lot, so there is a high chance of dropping it or knocking it off. 

How Do I Mic My Acoustic Guitar?

Here are some useful tips and guidelines:

  1. Place the mic about nine inches away from the guitar.

  2. Point the mic towards the area where the fretboard meets the body – this will help you get balanced string sounds. Do not place it right at the soundhole or you will have too many low ends.

  3. If you have an omni-directional mic, place it in line with the soundhole, but around one foot away. If you move it closer or further away, you can change the tone and balance the sounds against the room sounds – if you have an omni-directional mic, there will be no increased low end.

  4. A small-diaphragm condenser mic should be placed towards the 12th fret in order to capture a bright sound. 

Overall, the best you can do is just practice until you find your favorite mic position. The guidelines are some of the most common placements, but there are also some less common ones – such as having two small diaphragm condensers where one is at the 12th fret and the second is toward the body. Whatever rocks your boat!


All in all, when it comes to recordings, and also in stage performing, mics are necessary for acoustic guitars, given their limited volumes. We presented you with the best mics for acoustic guitars, which allow you to preserve the natural sounds of your instrument, without feedback or unwanted noise and feature great price tags for all pockets!
