To record acoustic guitar, point a single microphone at the 12th fret from 6–12 inches away, angled slightly toward the soundhole — because where you put the mic changes the sound far more than which mic you use. Moving a microphone six inches will transform a recording; swapping a budget condenser for an expensive one usually will not.
Quick Answer
- Aim at the 12th fret, not the soundhole. The soundhole is where the low-end energy escapes — point a mic straight into it and you get a boomy recording no EQ fully rescues.
- One good mic beats two badly placed ones. Two mics introduce phase cancellation, and a phase-cancelled stereo pair sounds thinner than a single mono mic every time.
- Proximity effect is why your close-miked guitar sounds muddy in the mix. Cardioid mics boost bass as they get closer; inside about 6 inches that boost is substantial and it stacks up badly under a vocal.
- Record one to two days after changing strings. Fresh strings are bright and slightly unstable for the first couple of hours of playing, then settle into their best recorded tone before going dull.
- In an untreated room, get closer. More distance means more room, and if the room is the weak link — which at home it almost always is — distance is the enemy rather than the goal.
Best for: songwriters recording demos at home who have a decent guitar and a usable mic, and whose recordings still sound boomy, thin, or distant compared to what they hear in the room. Skip if: you’re tracking in a treated studio with an engineer, or you’re capturing quick ideas on a phone and are happy with that — nothing here will make a voice memo worse, but none of it is necessary either.
Time cost, honestly: the 12th-fret starting position takes about two minutes and improves most home recordings immediately. The nine-position map in the level-up section takes roughly 40 minutes once, and the result — knowing where your guitar sounds best in your room — doesn’t need repeating unless you change guitar or room. After that it’s 10 minutes a day for a fortnight to make good placement automatic rather than something you rediscover each session.
Where should I put the mic to record acoustic guitar?
Start with the microphone pointed at the 12th fret, 6 to 12 inches from the strings, angled slightly back toward the soundhole. That position is the standard starting point because it balances the two problems at either end of the instrument: too far toward the soundhole and you capture excessive low-mid boom, too far toward the bridge and the sound turns thin and percussive.
It is a starting point, not an answer. Every guitar has a slightly different sweet spot, which is what the nine-position map is for.
Why does pointing the mic at the soundhole sound bad?
Because the soundhole is a bass port. It’s where the guitar’s low-frequency energy is projected, so a microphone aimed directly into it captures a disproportionate amount of low-mid energy — the result reads as boomy, woolly, and indistinct.
It also sounds fine in isolation, which is the trap. A soundhole-heavy recording feels warm and full on its own and then disappears into mud the moment a bass part or a vocal sits over it.
TEST 1 — THE SOUNDHOLE PROOF
Setup: One mic, [YOUR GUITAR], record-enabled, gain set
Do this: 1. Record 8 bars aimed straight at the soundhole
2. Without changing gain, record the same 8 bars
aimed at the 12th fret
3. Listen to each on its own — the soundhole
version may sound "bigger"
4. Now play each one UNDER a rough vocal or a
bass part
Pass: You can hear the soundhole version lose definition
under the other part while the 12th-fret version
holds its place.
Why: Judging guitar tone in isolation is what produces
boomy demos. Judge it in context, always.Why does my acoustic sound muddy when I mic it close?
Proximity effect. Directional microphones — cardioid, supercardioid, figure-8 — increase bass response as they get closer to a source. Inside roughly six inches the boost becomes substantial, and on an acoustic guitar it piles onto frequencies that were already the instrument’s loudest.
Two fixes: back off to 8–12 inches, or use an omnidirectional microphone, which exhibits no proximity effect at all. Omnis also capture more room, which is a trade rather than a free solution.
What kind of microphone is best for acoustic guitar?
A small-diaphragm condenser is the conventional answer because it captures transient detail — the pick attack, the string articulation — accurately. But the choice matters far less than placement, and in an untreated room the “worse” mic is often the better one.
| Type | Character | Best when |
|---|---|---|
| Small-diaphragm condenser | Accurate, detailed, fast transients. The classic acoustic mic | Your room is decent and your guitar sounds good to begin with |
| Large-diaphragm condenser | Warmer, fuller low-mids, often flattering rather than accurate | You want the guitar to sound bigger than it is, or you’re also recording vocals with it |
| Dynamic | Less detail, rolled-off top, rejects more of the room | Untreated or noisy room — genuinely the right call more often than people admit |
| Ribbon | Smooth, darker, figure-8 pattern rejects sound from the sides | Bright guitar, harsh room, or you need side rejection |
Should I use one mic or two on acoustic guitar?
One, until you can reliably get a good sound with one. A single well-placed microphone produces a focused, mono-compatible recording with no phase problems. Two microphones introduce phase cancellation, and a phase-cancelled pair sounds thinner and weaker than either mic alone.
Stereo is worth it when the guitar is the only instrument, or when you want width in a sparse arrangement. In a dense demo with vocals, bass and drums, a mono acoustic usually sits better anyway.
What stereo mic technique should I use for acoustic guitar?
Three worth knowing. XY places two cardioid capsules as close together as possible, angled roughly 90° apart — narrow image, excellent mono compatibility, effectively no phase risk. ORTF spaces two cardioids 17 cm apart at 110° — wider image, still reasonably mono-safe. Mid-Side uses a cardioid and a figure-8, and lets you adjust stereo width after recording, which is the most forgiving option if you’re unsure.
If you’re recording demos rather than an album, XY is the safe default.
What is the 3:1 rule and why does it matter?
When using two microphones on one source, the distance between the mics should be at least three times the distance from each mic to the source. If a mic sits 8 inches from the guitar, the second mic should be at least 24 inches away from the first.
The rule reduces phase cancellation — the frequency-dependent thinning that happens when the same sound arrives at two mics at slightly different times. It’s a guideline rather than physics, but ignoring it is the most common reason a two-mic acoustic recording sounds worse than a one-mic one.
TEST 2 — THE PHASE CHECK
Setup: Two mics on the guitar, both recorded to
separate tracks, same take
Do this: 1. Play both tracks together, panned centre
2. Flip the POLARITY (Ø) button on one track
3. Listen to the low end specifically
Pass: The version WITHOUT the flip sounds fuller.
That's correct polarity.
Fail: The FLIPPED version sounds fuller — you had a
phase problem. Keep it flipped, or better,
move a mic and re-record.
Also: If neither sounds clearly better and both sound
thin, your mics are too close together. Apply
the 3:1 rule and try again.
Takes: 90 seconds. Do it every time you use two mics.Faster than rediscovering this every session: the [LEAD MAGNET: Acoustic Recording Setup Card] is a one-page reference — the nine-position map grid, the phase check, the stereo technique specs, and a room-fix checklist, sized to sit on a music stand next to you while you set up. Details below →
How do I stop my room ruining the recording?
Get closer to the guitar and get the guitar away from hard parallel surfaces. Distance is what lets the room into a recording, so in an untreated space a closer mic is simply a better mic.
Beyond that: avoid recording in the centre of a square room, keep out of corners, and put something soft behind the microphone and behind yourself — a duvet on a mic stand, an open wardrobe of clothes, a sofa. You’re not trying to build a studio, only to stop the first reflections reaching the mic.
TEST 3 — THE CLAP TEST
Setup: You, in [ROOM], no gear needed
Do this: 1. Stand where you'd record. Clap once, sharply.
2. Listen to what happens after the clap.
3. Move to three other spots in the same room.
Clap in each.
Pass: One spot has a noticeably shorter, drier decay
with no audible "ring" or flutter after the clap.
Record there.
Fail: Every spot rings. Add soft material — bedding,
coats, a sofa moved in — and clap again.
Note: A flutter echo is the fast metallic "brrrp"
after a clap between two parallel hard walls.
If you hear it, you are standing in the worst
possible place. Move.
Takes: Three minutes. Do it once per room, forever.Why does my recorded guitar sound different from how it sounds to me?
Because you hear your guitar from above and behind it, blended with the whole room. A microphone hears one small area from one angle, with no blending. That gap is normal and it’s why a recording can sound thin or nasal when the instrument sounds fine to you.
It also means fixing the recording is usually a placement problem rather than a guitar problem — you’re not making the guitar sound wrong, you’re aiming at the wrong part of it.
What should I change about my playing when recording?
Play more evenly and slightly more gently than you would live. Microphones exaggerate dynamic inconsistency, so a heavy accent that reads as expressive in a room can read as a spike on a recording. Fret-hand movement, breathing, chair creak and clothing rustle all become audible in a way they never are when you’re playing to people.
The single biggest improvement most players can make costs nothing: keep the guitar still. Body movement changes the mic-to-source distance continuously, which produces a wandering tone no amount of mixing corrects.
DRILL — PLAYING STILL
Play: [8 BARS OF YOUR SONG], recorded
Tempo: Your song's tempo, click on
Reps: 3 takes per session, 5 sessions
Steps: 1. Take one: play normally. Don't think about it.
2. Take two: plant both feet, keep your torso
still, move only your arms.
3. Take three: same, and lighten your right hand
by about 20 percent.
4. Listen to all three back to back.
Done when: you can hear which take was which without
looking at the labels — and take three is
usually the one you keep.
Note: Recording rewards consistency over intensity.
Live playing rewards the reverse. That switch
is a skill, not a compromise.When should I change strings before recording?
One to two days before, not the same day. Brand-new strings are bright and slightly unstable — they stretch, drift out of tune, and can sound glassy on a recording. After a couple of hours of playing they settle into their best recorded tone, and they stay there for roughly a week of moderate use before going dull.
If you’re recording a full demo, change strings, play for an evening, then record the next day.
What do most people get wrong when recording acoustic guitar?
| Problem | What most people do | What actually works |
|---|---|---|
| Boomy recording | EQ out the low end afterwards | Move the mic away from the soundhole toward the 12th fret. Fix it at the source, not in the mix |
| Thin recording | Boost the bass with EQ | Move the mic slightly toward the soundhole or a little closer. Boosting bass that was never captured just amplifies noise |
| Wanting a better sound | Buy a more expensive microphone | Move the mic you own. Six inches of position changes more than $1,000 of mic |
| Wanting stereo width | Set up two mics wherever they fit | Use XY, or apply the 3:1 rule and check polarity. Otherwise mono is genuinely better |
| Bad room | Add reverb to “fill it out” | Get closer to reduce room, then add reverb deliberately afterwards. Captured room can’t be removed; added reverb can |
| Judging the tone | Listen to the guitar track solo | Listen under a rough vocal. Solo tone and mix tone are different targets and the second one is the job |
Worked example: fixing a boomy fingerpicked demo
Composite from teaching sessions. Positions and settings are real; the song is not named.
Input — the complaint. “My fingerpicked demo sounds great on its own and disappears when I add the vocal.” Setup: dreadnought, large-diaphragm condenser at roughly 4 inches from the soundhole, spare bedroom, no treatment, cardioid pattern.
Step 1 — identify the three stacked problems. Not one fault, three, and each one compounds the others:
DIAGNOSIS
1. AIMED AT THE SOUNDHOLE
→ capturing the guitar's bass port directly
2. FOUR INCHES AWAY, CARDIOID
→ proximity effect adding substantial low end
on top of problem 1
3. DREADNOUGHT
→ the largest-bodied common acoustic, already
the bassiest starting point
Three low-end problems stacked. The recording isn't
boomy by accident — it's boomy three times over.Step 2 — the fix, in order, costing nothing:
FIX SEQUENCE
1. Move the aim from the soundhole to the 12th fret
→ removes the direct bass-port capture
2. Move from 4 inches out to 9 inches
→ proximity effect drops substantially
3. Angle the mic ~15° back toward the soundhole
→ recovers some body without aiming into the port
4. Re-set gain (the signal will now be quieter)
→ peaks to −12 dBFS, set from the loudest passage
No EQ. No new gear. No plugin.Step 3 — the listening test that confirmed it. Both versions played under the same rough vocal:
Before: solo, warm and full. Under the vocal, the guitar and the vocal’s chest register fought for the same space — the guitar became a low rumble and lost its picking definition entirely.
After: solo, noticeably thinner and slightly disappointing on its own. Under the vocal, the picking pattern stayed audible and the vocal sat on top without either part being turned down.
Output — the counterintuitive lesson. The better recording sounded worse in isolation. That’s the point, and it’s why judging acoustic tone solo produces demos that collapse in the mix. The right question is never “does this sound good?” — it’s “does this sound good under the vocal?“
Guitar-side note. For a dreadnought specifically, moving slightly further toward the neck than the standard 12th fret — around the 14th — is often the better landing spot, because the body is contributing so much low end already. On a smaller-bodied guitar the reverse tends to be true.
Level-up: the nine-position map
The section competing guides won’t have, because it produces an answer specific to your instrument rather than a general rule.
Every guitar and room combination has its own sweet spot. “12th fret, 8 inches” is a starting point derived from averages. This procedure finds yours in about forty minutes, once, and you never have to guess again.
THE NINE-POSITION MAP
Record the SAME 8 bars at each of nine positions.
Same take, same dynamics, same gain, no EQ.
DISTANCE FROM STRINGS

RULES
· Same 8 bars, same tempo, every time. Use a click.
· Do NOT adjust gain between positions. You are
comparing tone, and a gain change contaminates that.
· Label every take by number as you record it.
· Do not listen until all nine are recorded.
THEN — and this is the part that matters:
1. Level-match all nine so they're the same loudness
2. Listen BLIND — have someone shuffle them, or
rename the files randomly
3. Rank your top three WITHOUT knowing which is which
4. Now play your top three under a rough vocal
5. Re-rank. The order usually changes.
Done when: you can name your guitar's position from
memory — "mine is 14th fret at 9 inches" — and you set
up in ninety seconds instead of twenty minutes.
Repeat only when you change guitar or room.Why blind and level-matched
Because louder sounds better and expectation sounds better. If you know take 5 is the classic position you will hear it as correct, and if one take is 2 dB louder you will prefer it regardless of tone. Level-matching and blind ranking remove both biases, and they’re the only reason the exercise produces a real answer rather than a confirmation of what you already believed.
What the map usually reveals
- Large-bodied guitars — dreadnoughts and jumbos — tend to prefer positions 1–3, further toward the neck, because the body already supplies plenty of low end.
- Small-bodied guitars — parlours, concerts, 000s — often prefer 7–9, nearer the soundhole, which gives back the body they lack.
- Untreated rooms push the answer toward the 6-inch column, because less distance means less room.
- Fingerstyle usually lands nearer the neck than strumming, because the attack detail matters more than the body.
The 30-day plan: 10 minutes a day
═══════════════════════════════════════════════
WEEK 1 — POSITION
10 min/day
Day 1 : TEST 1 — the soundhole proof. Record both,
judge under a vocal.
Day 2 : TEST 3 — clap test. Find your room's best
spot and mark it with tape.
Day 3–5 : Record the same 8 bars from three distances:
6", 9", 12". Same aim point. Compare.
Day 6–7 : Same 8 bars from three aim points at your
best distance: soundhole edge, 12th, 14th.
Goal : you can hear distance and aim as two separate
variables rather than one vague "sound."
═══════════════════════════════════════════════
WEEK 2 — THE MAP
10 min/day
Day 8–10 : Record all nine positions. Two or three
per session. Label as you go.
Day 11–12 : Level-match all nine. Listen blind.
Rank your top three.
Day 13–14 : Play your top three under a rough vocal.
Re-rank. Write the winner on tape and
stick it to your mic stand.
Goal : one position, chosen blind, verified in context.
═══════════════════════════════════════════════
WEEK 3 — PLAYING FOR THE MIC
10 min/day
Day 15–17 : The playing-still drill. Three takes,
five days.
Day 18–19 : Record with headphones on, monitoring
yourself. Notice every squeak, breath and
chair creak you've never heard before.
Day 20–21 : Re-record the same part deliberately
eliminating the three worst noises.
Goal : your takes get quieter and more even without
getting stiffer.
═══════════════════════════════════════════════
WEEK 4 — IN CONTEXT
10 min/day

week 1. Write down what specifically
changed, and which change did the most.
Goal : you can set up and get a usable acoustic
sound in under five minutes.

Frequently asked questions
Where do you point a microphone to record acoustic guitar?
At the 12th fret, from 6 to 12 inches away, angled slightly back toward the soundhole. That position balances body and definition — aiming at the soundhole captures the guitar’s bass port and produces a boomy recording, while aiming at the bridge sounds thin and percussive. Treat it as a starting point and adjust for your guitar’s body size.
What is the best microphone for recording acoustic guitar?
A small-diaphragm condenser is the conventional choice because it captures transient detail accurately. But microphone choice matters far less than placement, and in an untreated room a dynamic microphone often produces a better result because it rejects more of the room. Moving the mic you already own six inches will change the sound more than upgrading it.
Why does my acoustic guitar recording sound boomy?
Usually three stacked causes: the mic is aimed at the soundhole, which is the guitar’s bass port; it’s closer than about six inches, which triggers proximity effect on a directional mic; and the guitar is large-bodied. Fix it at the source by aiming at the 12th fret and moving to 9 inches, rather than trying to EQ the low end out afterwards.
Should I record acoustic guitar in mono or stereo?
Mono, unless the guitar is the only instrument. A single well-placed microphone is focused and has no phase problems, whereas two mics introduce cancellation that makes the result thinner than either mic alone. In a dense demo with vocals and bass, mono acoustic almost always sits better in the mix anyway.
What is the 3:1 rule in recording?
When two microphones record one source, the distance between the mics should be at least three times the distance from each mic to the source. If one mic sits 8 inches from the guitar, the second should be at least 24 inches from the first. The rule reduces phase cancellation, which is the most common reason a two-mic recording sounds worse than a one-mic one.
How do I record acoustic guitar in a bad room?
Get closer to the guitar, because distance is what lets the room into the recording. Then do a clap test to find the driest spot in the room, avoid the centre and the corners, and put something soft behind the microphone and behind yourself — bedding, coats, an open wardrobe. You aren’t building a studio, only stopping first reflections reaching the mic.
When should I change strings before recording?
One to two days beforehand. Brand-new strings are bright and unstable — they stretch, drift out of tune, and can sound glassy on a recording. After a couple of hours of playing they settle into their best recorded tone and hold it for roughly a week of moderate use. Change them, play for an evening, then record the next day.
Why does my recorded guitar sound different from how it sounds in the room?
Because you hear your guitar from above and behind it, blended with the entire room, while a microphone hears one small area from one fixed angle with no blending. The gap is normal and it means the fix is usually placement rather than the instrument — you’re aiming at the wrong part of a guitar that sounds perfectly good.

Changelog: Initial publication as a Songwriting Studio cluster child. Nine-position map added as the level-up, with blind and level-matched listening protocol. Body-size starting positions added. No prices or model names included by design — those live in the linked child buying guides.
Next review due: 27 August 2026.
Review cadence: every 7–14 days. Because this guide carries no prices and the underlying technique is stable, it decays far more slowly than the product posts it links to — update the visible date only when a drill, claim or example materially changes. Google’s helpful-content guidance flags date-stamping otherwise-unchanged pages as a low-quality signal.
Version notes
- No prices or model names by design. Specific microphones and current pricing belong in the child buying guides, where the exact-price-plus-source-plus-checked-date format already runs. Do not add them here — it creates a second maintenance surface, and stale prices are the fastest way to lose a citation.
- Stereo technique specifications — ORTF at 17 cm / 110° is a defined standard. XY is conventionally 90°, though 90–135° is in common use; if you add a figure, state the range rather than a single number.
- Distances and aim points — conventional starting positions, presented as such. They are not measured optima and the guide says so. Do not tighten them into absolutes in future edits.
- The nine-position map — the blind, level-matched listening protocol is the load-bearing part. If the section is ever shortened, keep the blind ranking and drop something else; without it the exercise only confirms what the reader already expected.
- Tool and publication links — four resources listed, current at publication. Re-verify at each review and log dates here.
