Recording acoustic guitar well is one of the most rewarding — and most misunderstood — skills in music production. The guitar sounds beautiful in the room, but the recording sounds boxy, boomy, or thin. Or the placement sounds fine but everything else falls apart. The good news is that most acoustic guitar recording problems have straightforward solutions. This guide covers everything you need to capture professional-quality acoustic guitar recordings in your home studio, from microphone selection through placement techniques to mixing.
Place a condenser microphone 12-16 inches from the guitar's 12th fret, angled slightly downward toward the soundhole—this single positioning principle captures the instrument's natural tone while minimizing boxiness and boominess. Combine fresh strings (preferably coated) with proper mic placement and the 3:1 phase rule for stereo recordings to achieve professional-quality acoustic guitar sound in your home studio.
What You Need
Before placing a single microphone, make sure you have the fundamentals covered. Fresh guitar strings make an enormous difference — the wound strings that have oxidized for months produce a dull, muted recording with pronounced finger squeak. Put on a new set before any important recording session. Coated strings (Elixir, D'Addario XT) reduce finger squeak significantly and last longer while maintaining brightness.
You need at minimum: one microphone (preferably a condenser), an audio interface with at least one microphone preamp, a microphone stand with boom arm for flexible positioning, and a quiet recording space. Optional but useful: a second microphone for stereo recording, basic acoustic treatment, a pop filter or foam windscreen for close-miking.
Microphone Selection
Condenser microphones are the standard choice for acoustic guitar recording because they capture the full frequency range of the instrument — from the deep body resonance through the fundamental string frequencies to the high-frequency sparkle of steel strings and fret articulation. Large-diaphragm condensers produce a warmer, fuller sound with more body. Small-diaphragm condensers produce a more accurate, detailed capture with faster transient response that some engineers prefer for fingerpicking guitar parts.
| Microphone | Type | Character | Best For | Price |
|---|---|---|---|---|
| Audio-Technica AT2020 | LDC | Clean, forward | Budget strumming and fingerpicking | ~$99 |
| Rode NT1 5th Gen | LDC | Open, detailed, low noise | Vocals and guitar, home studio | ~$249 |
| AKG C414 XLII | LDC multipattern | Bright, airy presence boost | Professional studio, multiple sources | ~$1,279 |
| Shure SM57 | Dynamic | Thick, focused, forgiving | Dense mixes, loud room, live | ~$99 |
| Rode M5 (pair) | SDC | Accurate, fast transients | Stereo recording, detailed fingerpicking | ~$199 |
Dynamic microphones like the Shure SM57 work on acoustic guitar and produce a tighter, more focused capture with less room pickup. In untreated rooms or dense musical contexts where the guitar needs to sit back in the mix rather than dominate, a dynamic mic is sometimes the better practical choice. Do not let anyone tell you that a dynamic cannot produce a professional acoustic guitar recording — Steve Albini has used dynamic microphones on acoustic guitar to exceptional effect on major commercial recordings.
Single Microphone Placement
The most common beginner mistake is pointing the microphone directly at the soundhole. It seems logical — the sound comes from there — but the soundhole concentrates low frequencies that produce a boomy, uncontrolled recording with too much bass and too little character. The soundhole is the worst single point to aim a microphone at on an acoustic guitar.
The best starting position for a single microphone is 10–12 inches from the guitar, aimed at the 12th fret or the area where the neck meets the body of the guitar. Move your head around the guitar before placing the mic and listen for where the guitar sounds most balanced — where the body resonance and string articulation both come through clearly. That is where your microphone should be.
Position 1: 12th Fret, 10–12 Inches
The standard starting position. Captures balanced body resonance and string detail. Neutral and usable in almost any context. Start here before experimenting elsewhere.
Position 2: Over the Shoulder
Position the mic at the player's ear level, pointing down at the guitar. Captures what the guitarist hears. Often produces a natural, musical result that sits well without EQ.
Position 3: Bridge Area, Off-Axis
Aimed at the bridge from 10–14 inches above the soundhole but pointing slightly away. Emphasizes body and warmth. Good for fingerpicking styles where low-end presence is desirable.
Position 4: Toward the Fretboard, Angled In
Positioned above and toward the nut end, angled toward the sound hole. Captures more string and fret articulation, less body resonance. Good for picking-heavy parts in busy arrangements.
Distance matters enormously. At 6 inches, proximity effect (low-end buildup in cardioid pattern mics) is significant — the guitar sounds fuller but potentially boomy. At 18–24 inches, you capture more room ambience and the natural acoustic bloom of the guitar in the space. In untreated rooms, staying at 8–12 inches reduces the capture of room reflections while still producing a natural-sounding recording.
Stereo Recording Techniques
A stereo acoustic guitar recording creates width, depth, and natural space that a single mono microphone cannot produce. However, stereo recording also introduces phase relationship complexity — if your two microphones capture the same sound at slightly different times, combining them to mono causes cancellation that makes the guitar sound thin and hollow. Understanding three reliable stereo techniques protects against this.
XY (Coincident Pair). Place two small-diaphragm condenser microphones with their capsules as close together as physically possible — essentially touching at the same point in space — angled apart at 90 degrees, both aimed at the 12th fret area. Because the capsules share nearly the same point in space, sound reaches both at essentially the same time and phase issues are minimal. XY produces a natural, focused stereo image that collapses cleanly to mono. This is the most reliable stereo technique for producers new to multi-mic recording and the best starting point for acoustic guitar stereo work.
Spaced Pair (AB). Place two microphones several inches to feet apart, both aimed at the guitar. The spaced pair captures a wider, more enveloping stereo image than XY but introduces time delay between the two signals that causes phase issues when summed to mono. Follow the 3:1 rule: the second microphone should be at least three times further from the first microphone than the first microphone is from the guitar. If your primary mic is 10 inches from the guitar, the second mic should be at least 30 inches from the first. Combining a large-diaphragm condenser at the 12th fret with a small-diaphragm condenser positioned near the body produces complementary captures that blend naturally.
ORTF. The ORTF technique positions two cardioid microphones 17 centimeters apart, angled at 110 degrees to each other, pointed at the guitar. It is a standardized stereo technique developed by French Radio that captures a stereo image with more width than XY while maintaining better mono compatibility than wide spaced pairs. Requires two microphones of the same model (a matched pair) for best results.
The Recording Environment
The room is the third instrument in any acoustic recording after the guitar and the microphone. A bad-sounding room produces bad-sounding recordings regardless of how good your other equipment is. You cannot EQ away flutter echo or remove the boxy reflections of an untreated concrete-walled room in post-production.
In a home studio, use the softest-sounding room available. A bedroom with carpet, a bed, heavy curtains, and bookshelves is already relatively well-treated acoustically compared to a kitchen or bathroom. Record away from parallel walls to reduce standing wave buildup. Position the guitarist in a corner with acoustic panels or heavy blankets hung behind them to create an absorption zone behind the microphone's rejection pattern.
Choose your recording time strategically. Air conditioning, refrigerators, traffic noise, and neighbor activity all produce noise floor that your microphone captures. In a quiet time — early morning or late night — you may find your effective noise floor drops 10–15dB compared to the middle of a busy afternoon. This makes more difference to recording quality than almost any equipment upgrade at the home studio level.
Gain Staging for Acoustic Guitar
Set your preamp gain so that the loudest peaks in your acoustic guitar performance reach around -12 to -6dBFS on your DAW's level meter. This gives you headroom for louder moments while keeping the signal well above the noise floor. Do not record at maximum gain — acoustic guitar has dynamic range that exceeds what a maximally gained signal can capture without clipping. Record a representative section of the performance at your intended settings before committing to the full take.
Starting point gain settings:
Condenser mic (Rode NT1, AKG C414): 40–55% gain on interface
Dynamic mic (SM57 on acoustic): 65–80% gain on interface
Target level: -18 to -12dBFS average, peaks no higher than -6dBFS
Sample rate: 44.1 or 48kHz (96kHz if heavy processing planned)
Bit depth: 24-bit (always)
Common Mistakes That Ruin Acoustic Guitar Recordings
Pointing at the soundhole. The single most common mistake. Always angle slightly away from or above the soundhole to avoid the low-frequency buildup concentrated there.
Recording with old strings. Dull strings produce dull recordings. Fresh strings on the day of recording are not a luxury — they are a technical necessity for quality results.
Too much room in the recording. In untreated rooms, pulling the microphone too far from the guitar captures more room than guitar. Stay within 6–14 inches unless you have genuine acoustic treatment or a naturally well-sounding room.
Ignoring phase when using two microphones. Record a two-mic take, zoom in on the waveforms in your DAW, and check that the peaks align. If they are offset by a time delay, nudge one track until they align. Then listen in mono to verify there is no significant cancellation. Fixing phase at this stage saves hours of mixing frustration later.
Heavy compression during recording. Compressing aggressively at the recording stage removes dynamic information that cannot be recovered. Record without or with very gentle compression. Apply compression during mixing where you can adjust and undo.
Not listening with headphones in the room. Before you commit to a microphone position, put on headphones and listen to what the microphone is actually capturing while the guitarist plays. What you hear in the room and what the microphone hears are often surprisingly different. Three minutes of positional listening before committing to a take saves thirty minutes of wondering why the recording sounds wrong.
Mixing and EQ for Acoustic Guitar
A well-recorded acoustic guitar needs minimal processing. The goal of mixing is to help it sit in context with other instruments, not to correct problems that should have been solved at the microphone placement stage.
High-pass filter. Apply a high-pass filter at 80–100Hz to remove sub-bass content that the guitar does not produce musically but that takes up headroom and creates mud in the low end of the mix. In a bass-heavy production (with bass guitar and kick drum), push this higher — 120Hz is not unusual for acoustic guitar in a full band context.
Dealing with boxiness. A boxy, midrange-heavy sound that obscures clarity usually sits between 200–400Hz. A narrow cut of 2–4dB in this range often opens up an acoustic guitar recording dramatically. Find the exact frequency with a narrow-band boost, sweep until you identify the most unpleasant resonance, then convert it to a cut.
Adding sparkle. If the recording lacks the high-frequency sheen of the live instrument, a gentle shelf boost at 8–12kHz of 1–3dB adds air and openness without harshness. Be conservative — too much high-frequency boost creates sibilance and listening fatigue.
Compression. A moderate-ratio compressor (3:1 to 4:1) with a medium attack (20–40ms) and medium release (100–200ms) controls pick attack and evening out dynamic strumming without removing the natural feel of the performance. Attack time is crucial: too fast removes the transient pick attack that makes acoustic guitar recordings feel alive and immediate.
Reverb. A short room reverb (0.4–0.8 seconds) or plate reverb creates space and cohesion in the recording without washing out the detail. In a dense arrangement, use very short reverb with a pre-delay of 15–25ms to maintain the clarity of the dry guitar signal before the reverb blooms. In sparse arrangements, a longer, more ambient reverb creates the sense of performing in a real acoustic space.
Practical Exercises
Exercise 1: The Placement Comparison. Set up your microphone at five different positions — soundhole (to hear what not to do), 12th fret, over the shoulder, near the bridge, and angled from above. Record 30 seconds at each position. Listen back and identify how the character changes. This exercise, done once, will develop your ear for placement far faster than reading about it.
Exercise 2: Distance Testing. Choose your best position from Exercise 1. Record the same passage at 4 inches, 8 inches, 12 inches, 18 inches, and 24 inches. Listen back and compare the ratio of guitar to room at each distance. Identify the distance at which your room starts to become noticeable in the recording. Record at the distance just inside that threshold.
Exercise 3: Mono Check for Stereo Recording. If you have recorded a two-mic stereo take, pan both tracks to center and listen in mono. Does the guitar sound as full as in stereo, or does it thin out noticeably? Thin sound in mono indicates phase cancellation. Nudge the second track in time until the mono sound is as full as possible, then restore the stereo panning.
Practical Exercises
Position One Microphone for Acoustic Guitar
Position a cardioid condenser microphone approximately 12–18 inches from the acoustic guitar, aimed at the point where the neck meets the body (around the 12th fret). This position balances the brightness of the strings and the warmth of the body. Do not aim at the sound hole — it captures a boomy, unnatural tone with excessive low-end. Record a 2-minute take. Listen back and evaluate: is it too bright, too thin, or too boomy? Move the mic closer for more detail and body, further away for more room and naturalness. Adjust and record again. Three position adjustments teach you more about microphone technique than any manual.
Record a Stereo Acoustic Guitar Using Two Microphones
Set up a spaced pair: one condenser microphone at the 12th fret position (as per the beginner exercise) and a second microphone positioned at the body below the bridge, aimed at the lower bout. Pan the two microphones left and right in your DAW (±30–45 degrees). Check for phase issues: sum the two tracks to mono and verify the guitar doesn't sound hollow or thin compared to either track soloed. If it does, try flipping the phase of one track, or physically move one microphone slightly. When the mono sum sounds full and natural, your phase relationship is correct. A well-placed stereo pair produces a wider, more natural acoustic guitar sound than any post-processing technique.
Record and Mix a Layered Acoustic Guitar Part
Record the same guitar part 4 times. Takes 1 and 2: standard 12th fret position, panned left and right. Takes 3 and 4: microphone repositioned to the body position, panned slightly less wide (±15 degrees). This creates a 4-layer acoustic guitar stack with natural variation between takes. In your mix, EQ each layer differently: boost the 12th fret takes at 6–8kHz for string brightness, boost the body takes at 150–250Hz for warmth. When blended, the four layers should create a full, wide acoustic sound that fills the stereo field. Compare to a single-mic recording of the same part and evaluate the improvement in width and dimension.
Frequently Asked Questions
Boxy or boomy recordings typically result from improper microphone placement that captures too much of the guitar's body resonance. The guide emphasizes that mic placement is the single most important principle in acoustic guitar recording—positioning the mic correctly relative to the sound hole and fretboard will eliminate these issues and capture the natural balance of the instrument.
Large-diaphragm condensers (LDC) produce a warmer, fuller sound with more body, making them ideal for strumming styles. Small-diaphragm condensers offer more accurate, detailed capture with faster transient response, which some engineers prefer for fingerpicking parts. Your choice depends on the playing style and tone you want to achieve.
Changing to fresh guitar strings makes an enormous difference in your recording quality. Oxidized wound strings produce dull, muted recordings with pronounced finger squeak, while new strings maintain brightness and clarity. Coated strings like Elixir or D'Addario XT are particularly effective at reducing finger squeak while lasting longer.
The 3:1 phase rule is a principle used when recording with multiple microphones (such as stereo or multi-mic setups) to ensure proper phase relationships between microphones. This rule helps prevent phase cancellation and ensures that your stereo recordings maintain clarity and cohesion when mixed together.
The guide covers five specific placement positions with expected results for each, though the exact positions vary based on your desired tone. These placements address different areas of the guitar's sound—from capturing body resonance to highlighting fret articulation and string brightness—allowing you to choose the position that best suits your recording goals.
Yes, you can achieve professional results with a single condenser microphone, audio interface with preamp, microphone stand with boom arm, and a quiet recording space. The guide emphasizes that proper microphone selection and placement are more critical than having multiple microphones for capturing high-quality acoustic guitar recordings.
The guide covers both XY and spaced pair stereo recording techniques as methods for capturing stereo acoustic guitar recordings. Each technique produces different spatial characteristics and frequency response, allowing you to choose the stereo approach that best matches your desired sound and mixing style.
Acoustic treatment is listed as optional but useful for improving recording quality. While it's not absolutely necessary, basic acoustic treatment helps control room reflections and background noise, resulting in cleaner recordings. At minimum, you need a quiet recording space to avoid unwanted ambient noise in your acoustic guitar tracks.
Start at 10–12 inches from the guitar, aimed at the 12th fret or where the neck meets the body. Avoid pointing directly at the soundhole.
A condenser is generally preferred for its wider frequency response. A dynamic like the SM57 works well in dense mixes or untreated rooms.
The mic is likely too close to or aimed at the soundhole. Move it toward the 12th fret and apply an 80–100Hz high-pass filter.
Use coated strings, angle the mic away from the fretboard, and develop deliberate technique when changing chord shapes.
Two mics with capsules nearly touching, angled at 90 degrees, aimed at the 12th fret. No phase issues. Most reliable stereo technique for beginners.
Absolutely. A single well-placed condenser is standard practice and often sits better in a dense mix than wide stereo.
High-pass at 80–100Hz, cut 200–400Hz if boxy, gentle shelf boost at 8–12kHz if it lacks sparkle.
6–12 inches is the standard close-mic range. Further captures more room ambience.
The Audio-Technica AT2020 (~$99) or Rode NT1 5th Gen (~$249) are both excellent choices.
Mono in dense mixes. Stereo in sparse or singer-songwriter arrangements where width adds character.
