1 Why Acoustic Guitar Recording Is an Art
Recording acoustic guitar well is one of the most challenging tasks in home recording. Unlike electric guitar, where you can shape the tone endlessly with amp simulators and effects, acoustic guitar recording captures the actual sound of the instrument in your room. Every element matters: the quality of the guitar, the freshness of the strings, the microphone choice, its placement, the room's acoustics, and even your breathing and body movements. Getting it right requires patience, good ears, and an understanding of how microphones interact with the complex sound field of an acoustic guitar.
An acoustic guitar produces sound from its entire body, not just the sound hole. The top (soundboard) vibrates and pushes air, the sound hole projects mid and low frequencies, the neck and fretboard contribute brightness and attack, and the body sides and back add depth and resonance. A microphone placed in different positions relative to these sound sources captures dramatically different tonal qualities. This is why mic placement is the single most important variable in acoustic guitar recording.
The good news is that with one quality condenser microphone, a decent audio interface, and some knowledge of placement, you can achieve beautiful acoustic guitar recordings at home. The techniques described in this guide are the same ones used by professional recording engineers, and they do not require expensive equipment to implement. What they do require is careful listening and a willingness to move the microphone by inches until the sound is exactly right.
Before recording, prepare your guitar. Install fresh strings at least a day before the session so they have time to stretch and stabilize but still have their brightness. Check the guitar's intonation and make sure there are no buzzing frets or rattling hardware. Wipe down the strings and fretboard. A well-prepared acoustic guitar with fresh strings will record dramatically better than one with old, dead strings, regardless of how expensive the microphone is.
Pro Tip
The single biggest improvement you can make to your acoustic guitar recordings is putting on new strings 24 hours before recording. Old strings lose their harmonic content and sound dull and lifeless on recordings, even if they still sound acceptable to your ears when playing live. Fresh strings add clarity, sparkle, and detail that the microphone loves.
2 Microphone Types for Acoustic Guitar
Small-diaphragm condenser microphones are the most popular choice for recording acoustic guitar. Their extended high-frequency response and fast transient response capture the crisp attack of pick and fingertip on string with excellent detail. Models like the Rode NT5, AKG P170, Audio-Technica AT2021, and Neumann KM184 are studio standards. Small-diaphragm condensers produce a natural, uncolored sound that represents the guitar faithfully.
Large-diaphragm condenser microphones like the Audio-Technica AT2020, Rode NT1, and AKG C214 are also excellent for acoustic guitar. They tend to produce a slightly warmer, fuller sound compared to small-diaphragm models, with a subtle emphasis in the low-mid range that can flatter thinner-sounding guitars. Large-diaphragm condensers are more versatile (they also work beautifully for vocals), making them a smart first microphone purchase for a home studio.
Dynamic microphones like the Shure SM57 are not the first choice for acoustic guitar but can work in situations where you need to reject room noise or when the acoustic guitar is being recorded alongside a loud band. The SM57 captures less high-frequency detail than a condenser but produces a warm, focused sound that sits well in a dense mix. For solo acoustic recording or singer-songwriter work, a condenser is strongly preferred.
Ribbon microphones are a premium option that produces the warmest, most natural-sounding acoustic guitar recordings. They capture transients with a smooth, rounded quality that is flattering without being artificially colored. Ribbon mics like the Royer R-121 or the budget-friendly MXL R144 are beloved by engineers for their organic quality. However, they require high-quality preamps with plenty of gain and are more fragile than condensers, making them a better second microphone than a first purchase.
3 Single-Mic Placement Techniques
The most common and effective single-mic position for acoustic guitar is pointing the microphone at the 12th fret area, approximately 8 to 14 inches from the guitar. This position captures a balanced blend of the guitar's tonal spectrum: brightness and attack from the neck and strings, body and warmth from the soundboard, and enough low-end fullness without the boominess that comes from pointing directly at the sound hole.
Single-Mic Placement Positions
POSITION 1: 12th Fret (Most Common)
Mic points at the junction of neck and body
Distance: 8-14 inches
Result: Balanced tone, natural sound

POSITION 2: Between Sound Hole and Bridge
Mic points at the lower bout, below sound hole
Distance: 8-12 inches
Result: Warmer, fuller, more body
POSITION 3: Over the Shoulder
Mic placed behind the player's head, pointing
down at the guitar
Distance: 18-24 inches
Result: Natural "player's perspective" sound
AVOID: Pointing directly at the sound hole
Result: Boomy, unnatural bass buildup
Moving the microphone closer to the guitar increases bass response (due to the proximity effect inherent in directional microphones) and reduces room ambience. Moving it farther away adds more room sound and produces a more natural, airy quality but also picks up more background noise. For home studios with untreated rooms, closer placement (8-10 inches) is usually better because it minimizes the effect of room reflections.
The angle of the microphone matters as much as the distance. Pointing the mic directly at the strings captures more pick noise and transient detail. Angling it slightly away from the strings and toward the body reduces harshness and adds warmth. Angling it toward the neck side adds brightness. Small adjustments of just one or two inches, or a few degrees of angle, can transform the recorded tone. Always wear headphones and listen while you move the mic to find the sweet spot.
One often-overlooked factor is player movement. Guitarists naturally sway and shift while playing, and if the microphone is very close, even small movements change the tone significantly throughout the recording. Either discipline yourself to hold still, or move the microphone back to 12-14 inches where small movements have less tonal impact. A consistent distance between guitar and microphone throughout the recording is essential for a professional-sounding result.
Pro Tip
Use the "one fist" rule as a starting point: make a fist and place it between the microphone and the guitar at the 12th fret. That distance (roughly 4-5 inches from the guitar body) is a reliable starting position. Then move the mic in small increments while listening through headphones until the tone sounds right to your ears.
4 Stereo Miking for a Full Sound
Using two microphones in a stereo configuration produces a wider, more immersive acoustic guitar sound that fills the stereo field. Stereo recording is particularly effective for solo acoustic guitar or singer-songwriter performances where the guitar needs to sound big and present. There are several proven stereo techniques, each with its own character.
The XY (coincident pair) technique places two identical microphones at the same point with their capsules angled 90-120 degrees apart. One mic points toward the neck, the other toward the bridge. This creates a stereo image with excellent mono compatibility (the recording sounds good even when collapsed to mono). XY is the safest stereo technique and is recommended for beginners because it avoids phase issues that can occur with spaced microphones.
The spaced pair technique places two microphones several inches apart, one pointing at the 12th fret and another pointing at the bridge or lower bout. This creates a wider stereo image than XY, with a sense of space and depth. However, the spacing between mics can cause phase cancellation at certain frequencies if not carefully managed. Follow the 3:1 rule: the distance between the two mics should be at least three times the distance from each mic to the guitar. This minimizes phase problems.
A third option is the mid-side (M/S) technique, which uses one cardioid mic (mid) pointed directly at the guitar and one figure-8 mic (side) placed perpendicular. This technique offers adjustable stereo width in post-production, meaning you can make the recording wider or narrower after it has been captured. M/S provides perfect mono compatibility and is used extensively in professional studios, though it requires a figure-8 microphone and specific DAW processing to decode the stereo image.
5 Room Acoustics and Preparation
Your room's acoustics have a profound effect on acoustic guitar recordings. Sound from the guitar bounces off walls, floors, and ceilings, and the microphone captures these reflections along with the direct sound of the guitar. In a small, untreated room, these reflections can create a boxy, colored sound that muddies the recording. Even basic room treatment dramatically improves the clarity and quality of acoustic guitar recordings.
If you cannot treat your room permanently, use temporary absorption. Hang heavy blankets or duvets on mic stands or furniture around your recording position. Place a thick rug on the floor beneath your chair. Position yourself away from bare walls, ideally in the center of the room or at least three feet from any wall. These simple measures absorb early reflections that would otherwise color your recording.
Background noise is the enemy of acoustic guitar recording. Turn off fans, air conditioning, heaters, and any appliances that create noise. Close windows. Power down computers if possible (or at minimum, move the computer as far from the microphone as you can). Condenser microphones are extremely sensitive and will pick up noise sources that your ears have learned to ignore. Record a few seconds of silence and listen back to identify any noise issues before you start playing.
The time of day matters more than most people realize. Traffic noise, construction, barking dogs, and household activity all end up on your recordings if you use sensitive microphones. Early mornings, late evenings, and weekends tend to be the quietest times. Plan your recording sessions for these windows when possible. Professional studios are acoustically isolated from outside noise, but home studios rarely are, making timing a practical consideration.
Pro Tip
Record in a walk-in closet if you have one. The clothes hanging on all sides act as natural sound absorbers, creating a surprisingly dead, controlled acoustic environment. It may feel awkward, but the resulting recordings can be remarkably clean and professional sounding, rivaling rooms with expensive acoustic treatment.
6 EQ, Compression, and Mixing Tips
Even a well-recorded acoustic guitar benefits from careful EQ (equalization) during mixing. The most common issue is low-frequency buildup, especially if the mic was placed close to the guitar. Apply a high-pass filter starting around 80-100Hz to remove rumble and low-end mud without thinning the guitar's body. If the recording sounds boxy, cut a narrow band around 300-400Hz by 2-3dB. For added sparkle and string clarity, a gentle boost around 10-12kHz with a shelf EQ adds air without harshness.
Compression evens out the dynamic range of an acoustic guitar recording, taming loud peaks while bringing up quieter passages. Use a gentle ratio of 2:1 to 4:1 with a medium attack time (10-30ms) that lets the initial pick transient through before the compressor engages. A slow release time (100-200ms) creates a natural, transparent compression that most listeners will not notice. Aim for 3-6dB of gain reduction on the loudest peaks.
If you recorded in stereo, pan the two tracks to create the stereo image. For XY recordings, pan left and right to taste, typically 50-80% each direction. For spaced pairs, similar panning works well. If the acoustic guitar is the primary instrument (solo or singer-songwriter), a wide stereo spread sounds impressive. If it is sitting in a full band mix, narrow the stereo width or even use a mono recording to prevent it from taking up too much space in the mix.
Reverb adds depth and space to acoustic guitar recordings, especially if the room was dry. A small room or plate reverb with a decay time of 1-2 seconds adds a sense of space without washing out the detail. Use reverb sparingly; too much makes the guitar sound distant and unfocused. If you recorded with room ambience already captured by the microphone, you may need little or no additional reverb. For detailed guidance on the DAW tools used for mixing, see our dedicated guide.
