Quick-Access To The Best Budget Mics for Dynamic Acoustic Guitar Recordings👇

If you’re looking to find the best mic for acoustic guitar in the studio, then keep on reading.

An acoustic guitar recording, when done correctly, can sound absolutely divine. But capturing this great sound is something that plagues even the world’s top engineers.

The acoustic is an instrument that covers a huge range of the frequency spectrum. While the electric guitar likes to sit firmly in the mids, the acoustic loves the lows and highs equally. You need an acoustic guitar microphone that can capture this full range sound with ease.

There are a few things to consider about the tone of an acoustic guitar. The room the guitar sits in will play a part on the overall sound. The size of the body will give you varying degrees of low end and warmth. The way you pick will create more or less of a percussive element.

With so much to think about, it’s often tricky to figure out where to start with a microphone choice. Do you go for a small diaphragm mic to emphasize that top end sparkle? Or do you go for a large diaphragm mic to add that warm low end?

You’re about to find out the answers to those questions and explore the 17 best microphones for recording acoustic guitar. Your acoustic guitar will sound better than ever when you’re done here!

Small Diaphragm vs. Large Diaphragm for Acoustic Guitar

If you consider the difference from a recording perspective, you can split each diaphragm type into the characteristics they will offer your acoustic guitar recording.

Large diaphragm mics offer a much lower noise ratio compared to their smaller counterparts. If This is a bonus if you want to push the gain of the interface or preamp.

From a strict sound quality recording angle, small diaphragm mics are technically better suited to the job. The transient response of a small diaphragm microphone is a little tighter, and they have the ability to track percussive attack better. This is why they are used on drums a lot.

Small diaphragm microphones offer a pretty solid pick up pattern which is usually fairly tight in it’s capture area. This means, if you’re pointing it straight at something, it’s going to capture what it’s being pointed at, with less spill from the back and sides.

Large diaphragm microphones are better at capturing lower frequencies, a fuller sound, and a fuller dynamic range, while small diaphragm mics have a better extended high end range and are tighter in their response.

Neither option is right or wrong. The best way to determine which is the right one for you to record acoustic with is to try them both and use your ears. No spec sheet in the world is as honest as your own ears when it comes to working out what you want to capture.

More About Small And Large Diaphragms…

As mentioned earlier, the diaphragm is the membrane within a condenser mic that vibrates when sound waves hit it.  As the membrane vibrates, the distance between it and the fixed back plate changes.

This change in distance creates an electronic signal, and thus, sound is produced.

You will find that condenser mics are highly recommended as the best microphones for recording acoustic guitar, because they can capture the guitar’s fine, nuanced tones. You know: those warm, honey-like deeps, and the plaintive, crystal clear highs.

The terms “large diaphragm” and “small diaphragm” are often referred to when it comes to condenser mics, and you’re probably wondering what these terms mean.

Originally, a “large diaphragm” microphone was one with a membrane of one inch or more in diameter.  A “small diaphragm” microphone, had a membrane of 1/2 inch or less.

However, due to discrepancies with the metric system, modern microphones regularly flaunt these “rules.”

Now that you know what the terms mean, let’s move on to why they matter.

Why Does It Matter What Size The Diaphragm Is?

Technically speaking, a larger diaphragm condenser will capture more acoustic waves.  They also have a lower self-noise level. This means that these mics will capture more of your talent, and less of their own intrinsic operational noise.

That being said, a small diaphragm condenser has the ability to respond more accurately to sound waves.

Besides the technical aspects, the sound produced will influence your choice.  Large diaphragm’s tend to provide a bolder, fuller sound for acoustic instruments.

Whereas, small diaphragms provide a very neutral, exact replica of sound.

So, if you’re looking to add a certain lush richness to your overall tone, a large diaphragm condenser mic is one of the best microphones for recording.

But if, instead, you want a very true sonic picture and to leave the vibrancy to your talent, a small diaphragm condenser mic is probably one of the best microphones for you.

Frequently Asked Questions

What’s The Preferred Method For Recording Acoustic Guitar With A Mic?

You might think that the microphone ought to be directly in front of the guitar sound hole.

Don’t do this.  For most acoustic guitars, this will result in picking up more lower frequency (aka “boomy” sound) than the higher, expressive tones.  Instead, place the microphone between the 12th and 14th fret.

Additionally, don’t get too close to the guitar.  Proximity effect is a real thing, in which the recording is distorted by placing the microphone too close to the source (this is why a high SPL can also be important).

Instead, place a microphone somewhere between 6-12 inches away from the guitar, with the mic head pointing at the neck.

It can also be a good idea to place a pop filter in front of the mic.

What Type Of Polar Pattern Is Good For Acoustic Guitar?

A cardioid condenser mic, with a cardioid pickup pattern, is the most common choice among microphones for recording acoustic guitar.

This doesn’t mean other versions can’t be used- they are!  Omnidirectional polar pattern mics don’t experience proximity effect, which means you can mic acoustic guitars with these mics at extremely close range – an inch or two away from the neck is not unheard of.

You can also do the exact opposite, and take advantage of an acoustically fascinating recording space by placing an omni several feet away from the instrument.

Figure eight pickup pattern mics will experience more proximity effect, and do great work when placed above the neck a bit.  One cool thing you can try with figure eight polar pattern mics is using them for recording vocals and guitar at the same time.

This can give you something to play around with in post.

What Can I Do To Improve My Acoustic Guitar Recordings?

Obviously, quality begets quality, so you’ll want to improve your demos with one of the best microphones for recording acoustic guitars.

Make sure your instrument is in good condition, with good, new strings, and make sure you’re playing in a designated music room.

In order to properly mic your acoustic guitar, you’ll want to first make sure your recording area is sound proof.

Pay attention to anything that might impact the sound quality in your space, too, like furniture, pillows, or your steel robot collection… anything that might dampen or reflect the sound waves you’ll be creating.

How Much Should You Pay For A Mic?

The very best mics obviously have a higher price range. But that doesn’t mean that you can’t get an awesome mic for less, either! You can find mics in a variety of price ranges.

If you don’t have a ton of money to drop on the best mics, try grabbing a simple multiple pickup pattern mic priced in the sub $250 range (like the Avantone CK-1).

This mic will give you incredible value for the price, and will get you recording with little to no trouble!

In Closing…

If you’re looking for the best microphones for recording acoustic guitars, you’ve got seventeen solid options in different price brackets to check out from today’s article.

We focused on the differences between large and small sized diaphragms, with plenty of each option.

And of course, we talked mostly about condenser microphones, as condenser mics are more prone to give you that awesome sound quality that you will need for capturing the smooth tones of acoustic instruments.

While larges will create a big, lush, warm sound, smalls will give back exactly what you give them.

Choosing the right acoustic guitar recorder is certainly a challenge!

But truly, there’s no wrong answer, just the right sound for you. Grab a couple mics in your price range, along with a cheap pop filter, and try them both. Let us know what works.
