This gear guide is sponsored by Sweetwater and you can click through to their website to read customer reviews, check prices, or make a purchase, however all of the recommendations below have been made by the Gearank team.

Knowing how to record acoustic guitars is a fundamental skill in audio engineering as it teaches you concepts like proximity, phase, and tonality to name a few. Equally important is the gear to get it done, and a big chunk of that is having the best mic for acoustic guitar.

Choosing the right microphone to record acoustic guitar and learning the skill of guitar micing can be a challenge especially with so many on the market today. Among those, not every mic complements the sound of the acoustic guitar. Some microphones have frequency responses that sound great with vocals but end up making acoustic guitar sound brittle or thin. Many like to assume that any condenser mic will do the job but the most optimal might even be a dynamic mic or ribbon mic.

To help you narrow down your choices, I’ve personally selected the mics below to recommend based primarily on my personal experiences rather than Gearank Ratings as we do in most of our other guides.

Technology is a wonderful thing. It’s development in amplification and recording of instruments has given us the best coustic guitar pickups, the best acoustic preamps, the best acoustic amp, and the best wireless guitar systems.  But along with other audio engineers, I am old school, and prefer recording with microphones straight from the instrument.

In my opinion, acoustic guitar sounds better when recorded directly with a proper microphone.

Best Small Diaphragm Condenser Mics for Recording Acoustic Guitar

Shure SM81

97 out of 100. Incorporating 500+ ratings and reviews.


  • Does not have the same low frequency emphasis as large-diaphragm mics


  • Transparent and clear tonality akin to premium tube amps
  • Excellent SPL handling - from quiet to extremely loud sources
  • Sound quality among the highest in its price class
  • Lightweight and easy to position

The Shure SM81 is a cardioid condenser microphone that has a transparent and clear sound comparable to premium tube microphones.

Because of its small diaphragm design, the SM81 is lighter (1.63 lbs) and easier to position than most microphones of this design.

It handles loud sound sources handily with a max SPL (sound pressure level) of 136dB (146dB with the built-in Pad), and as such it captures the nuances of acoustic guitars much better - be it during loud strumming or when carefully fingerpicking. This also makes it capable of handling acoustic guitar amplifiers and other loud instruments.

The usual downside of small diaphragm mics is its lack of frequency response, but this doesn't seem to be very noticeable with the SM81. The SM81 gives you more sound quality per dollar than similarly priced microphones.

It's really hard to find fault with it, especially for acoustic guitars, other than its natural limitation of not having the same low frequency emphasis as large-diaphragm mics. The Shure SM81 is highly recommended for acoustic guitar and beyond, it is the best small diaphragm condenser for acoustic guitar.


  • Polar Pattern: Cardioid
  • Frequency Response: 20Hz-20kHz
  • Impedance: 150 ohms

sE Electronics sE7 Small-diaphragm Condenser Microphone - Matched Pair


  • Sensitive to handling noise


  • Rich tonal reproduction
  • Versatile
  • Matched pair ensures consistency
  • Very detailed

The sE Electronics sE7 is a great stereo pair for acoustic guitar recording duties. Its high-quality condenser capsule and cardioid polar pattern suit various instruments, including drums, guitars, and pianos. The microphone's switchable options, such as the -20dB attenuation pad and low-cut filter, provide flexibility for recording guitars in difference scenarios.

Having two mics positioned in a spaced pair or XY arrangement ensures high consistency and accurate localization for stereo recordings, making it ideal for acoustic guitar recording. Placing a matched pair over the sound hole gives a more "three-dimensional" acoustic guitar sound" with a more accurate bass response. The microphone's build quality, sound clarity, and versatility, combined with the precision stereo bar and metal road case in the matched pair, enhance convenience and portability.

However, the sE7 falls into a mid-range price category, which might be slightly expensive compared to budget options. Additionally, like most small-diaphragm condenser microphones, the sE7 can be sensitive to handling noise, so using a shock mount or proper mic stand is recommended. If you plan to record mostly acoustic guitar, this shouldn't be a problem.

The sE Electronics sE7 is a solid choice for those who prioritize sound quality and versatility in their recording setups.

  • Priced at a premium


  • Works great in a matched stereo pair
  • Minimal off-axis coloration
  • Famed Neumann build quality and feel
  • High sensitivity rivaling large-diaphragm mics

The Neumann KM 184 is a pencil style small-diaphragm condenser that can rival the sensitivity of large-diaphragm mics, while retaining high SPL handling.

It has a frequency range of 20Hz to 20kHz, which is similar to large-diaphragm mics, and this allows for highly detailed sound capture that I certainly appreciate.

Another great feature is its minimal off-axis coloration - great for recording acoustic guitars with a matched pair in an x-y or near-coincident formation.

As expected from Neumann, this mic has premium build quality and feel. High input gain proved to be no problem with its supremely quiet operation. It works stunningly well with acoustic guitars especially with stereo guitar micing techniques.

As an added bonus, it also makes quick work of orchestral instruments, hi-hats, cymbals, and even choirs. Some even go so far as to claim that the Neumann KM184 is the best pencil style condenser microphone, and we understand where they are coming from, especially when most who have used this mic would agree as you can see from the high ratings it gets.

There shouldn't be anything holding you back from getting this mic other than the price, but those who wisely invest in the Neumann KM 184 will be more than satisfied with what they get.

Not just great for single miking, Neumann has hit a home run for Stereo Recording with the KM 184. Its phase integrity and tolerance are its best selling points as using a matched pair makes for great sounding acoustic guitar recordings in stereo.

Best Dynamic Mics for Recording Acoustic Guitar

Shure SM57

96 out of 100. Incorporating 7600+ ratings and reviews.
Shure SM57 Dynamic Cardioid Microphone


  • Not for delicate sounding sources
  • Needs foam filter to avoid vocal plosives


  • Extremely versatile
  • Great frequency response for various sources
  • Amazing long term durability and ruggedness
  • High SPL handling

When I first started out with building my recording setup years ago, I had a only a few things on my wishlist: A Mac, a Focusrite interface and a Shure SM57. It's the one mic that every audio engineer I've encountered and interacted with told me to get first. I was told that it can record anything from drums to vocals to acoustic guitar. Eventually I would expand my mic collection but I always have a use for the Shure SM57.

The Shure SM57 was developed in 1959 by Ernie Seeler. Seeler actually despised rock music and hoped the mic would be used for orchestras. In a stroke of irony, the SM57 went on to be one of the mainstays of rock music thanks to its high SPL handling, frequency response and long term durability. The mic can also be seen gracing US Presidential podiums paired with the Shure A81WS foam windscreen.

Shure SM57 with A81WS Foam Windscreen
The Shure A81WS foam windscreen paired with the SM57 is the configuration most often seen on US Presidential podiums. Pardon the cat fur; it's an old mic.

"SM" Stands for (TV) Studio Microphone. Despite its initial development for TV, the SM57 is able to record almost anything in the studio save for the most quiet sound sources that require absolute detail. It excels in handling electric guitar, drums and aggressive screamed vocals (with a pop filter or foam windscreen).

The SM57 is versatile enough to be used on acoustic guitars. Instead of miking from a distance like you would a condenser, the SM57 sounds best when pointed closer to the guitar. This results in a recording with lots of attack and punch. It is perfect for tracks where the acoustic guitar is layered in rather than as a solo acoustic track.

What I don't like about the SM57 is how hit or miss it is with sung vocals. Some singers sound great on it without much work while others sound brittle. It's this single inconsistency that I find makes me reach for a good condenser microphone. Another is that it's not the best mic for spoken word or podcasts. That task is better suited to the Shure SM7b which has a bit more detail and low end extension. But at nearly 4 times the price, the SM7b is only marginally better than the 57 in a lot of other aspects.

All in all, I echo the words of my mentors in saying that EVERY studio has to have at least one SM57.

One final note, the SM57, along with the SM58, are two of the most counterfeited microphones in the market. Be sure to get yours from a reputable seller or retailer. The counterfeits do not sound remotely close to the originals despite many looking very convincing.

Things to Consider When Buying an Acoustic Guitar Mic


Since acoustic guitars produce similar frequencies to vocals, large diaphragm condenser microphones work great with them. These are widely available and versatile, making them a practical option, ideal for first timers and those working to a budget. The only downside would be the size especially for models with a shockmount. Removing the shock mount may be a hassle if it's your only mic for both acoustic guitar and vocals. Keeping it on for acoustic guitar may limit your positioning options.

Small diaphragm condenser mics and ribbon mics, with their high frequency response and high SPL capabilities, work considerably well with the acoustic guitar's inherent treble emphasis and varying dynamics. As such they remain to be the professional's choice when Recording Acoustic Guitar, as evidenced by their presence in many performance stages and recording studios. The resulting recorded sound of acoustic guitars are generally favorable, and can even be great for a singer songwriter who sounds good with a miked up acoustic.

While they are not advisable for for use as an all-around mic, they are ideal extra mics that can be used for acoustic guitars, miking other instruments and for adding space and realism to recordings. Small Diaphraghm mics tend to have more low frequency roll-off than their large diaphraghm counterparts which makes them more suited for use multi-miked recordings. A spaced pair with one pointed at the soundhole and one near the bridge can compensate for the low frequency loss as well as provide an option for more detail in strumming. Using X-Y or near-coincident mic patterns with small diaphragm condensers produces better stereo recordings than a spaced pair of large diaphragm condensers and are easier to position.

Polar Pattern

Cardioid is the most common polar pattern used on mic designs, because of its simplicity and effectiveness. It is especially great for capturing single sound sources like acoustic instruments, where you just move the mic around to find the sweet spot and start capturing.

Still, it won't hurt to have mics with multiple patterns because they can be useful for other purposes, like when capturing multiple instruments that play simultaneously. Do take note that different mics may have the same polar pattern but have different sensitivities at varying degrees of capture. Some may be suited for miking directly in front while others are better for capturing the room. Note that positioning can be a big factor to get a good sound, other factors include the guitar body, playing style,

dB Pads

Pads allow microphones to better handle loud sound sources, especially when positioned up close. And since volume and dynamics vary from player to player, mics with pads allow for easy compatibility and positioning. Remember not to over use, when your acoustic guitar sounds muddled, you may want to reposition instead of overusing your dB pads.


These days, most condenser mics are built like tanks with tough metal exteriors. This means they are more than capable of reliable recording acoustic guitar in a professional setting. Still, it pays to check the specs and pictures to see if the mic is solid. This is important because miking acoustic guitars require a bit more repositioning than when miking vocals, so there's always the tendency of bumping or falling off. As with all electronic devices, do handle with reasonable care.

Best Mic for Acoustic Guitar Selection Methodology

The first Edition was published in 2016. The current edition was published on May 26, 2024

Our methodology for selecting the best microphone for acoustic guitar is a bit different from most of the gear guides on While our recommendations are usually based on product ratings and the best selling mics, in this case we used a combination of professional judgement and ratings.

We created a short-list of 58 mics that we know from experience have properties that are well suited to recording acoustic guitars.

For this edition we ended up processing over 60,100 reviews, ratings and forum comments with the Gearank Algorithm to produce rating scores out of 100 for each mic. Our top picks were then sorted according to type for this guide. For more information about our methods see How Gearank Works.

    1. Thanks for pointing out that I made that mistake when editing this guide. I have now corrected the SM57 specifications.

  1. Why did you remove the Rode? I think it’s a fantastic microphone for voice and acoustic guitar. I tried the Technica, but found that it failed the clarity test. I know other people will hear different things. But I would have Rode at the too of my list.
