The best microphone for acoustic guitar captures the instrument’s natural balance — crisp string detail and warm body resonance — without harshness or boom. For most home recordists, a small-diaphragm condenser is the go-to, but large-diaphragm condensers and stereo pairs each have a place depending on the sound you want.
Quick answer: A small-diaphragm condenser like the Rode NT5, sE Electronics sE8 or Neumann KM 184 is the classic choice. For a fuller sound, a large-diaphragm Rode NT1 or AKG C214 works well; a matched stereo pair gives the most spacious result.
What to look for in a microphone for acoustic guitar
Acoustic guitar is detailed and transient-rich, so accuracy and transient response matter.
- Condenser is standard: Condensers capture the fast pick attack and shimmer that define a good acoustic sound. See condenser vs dynamic microphones.
- Diaphragm size: Small-diaphragm condensers excel at accurate transients and detail; large-diaphragm models add warmth and body. Our diaphragm size guide compares them.
- Polar pattern: Cardioid is most common; if your room is good, omni can sound very natural. See polar patterns explained.
- Phantom power: Condensers need 48V — see what phantom power is.
Best small-diaphragm condensers (the classic choice)
These “pencil” mics are the studio default for acoustic guitar because of their accuracy and detail.
- Rode NT5 / NT55: Affordable, available as a matched pair, and a reliable workhorse for acoustic.
- sE Electronics sE8: Clean, detailed and even-handed; excellent value for serious home recordists.
- Neumann KM 184: A studio reference for acoustic guitar — refined, natural and detailed if your budget allows.
Large-diaphragm and ribbon options
- Large-diaphragm condensers like the Rode NT1 or AKG C214 add warmth and a fuller low-mid body — useful for solo fingerstyle or a more intimate tone.
- Ribbon mics such as the Royer R-121 tame brightness and sound smooth on overly zingy guitars, though they need plenty of clean gain. Browse our pick of the best ribbon microphones if you want that smoother character.
How to choose the right mic for your situation
There is no single “best” microphone — the right choice depends on the guitar, the player and the part the recording has to play in a mix. Work through these questions before you buy.
- Solo or band? A solo fingerstyle piece benefits from a fuller, more detailed capture, so a large-diaphragm condenser or a stereo pair pays off. In a busy band mix, the guitar only needs to occupy a narrow slot, so a single small-diaphragm cardioid usually sits better and is easier to mix.
- How bright is your guitar? A new instrument with fresh strings and a bright top can sound harsh through an already-bright condenser. If yours leans zingy, a ribbon or a warmer large-diaphragm condenser will balance it; a darker guitar comes alive with a crisp small-diaphragm condenser.
- What is your room like? Cardioid mics reject more of the room, which matters if your space is untreated. An omni pattern sounds wonderfully open but only in a room that is genuinely worth capturing.
- Budget and growth: If you can stretch to a matched pair rather than a single mic, you gain stereo and a spare for vocals or overheads later. A versatile cardioid condenser earns its keep across far more sources than a specialist mic. You will also need an interface with clean preamps, so see our best audio interfaces for guitar.
Mic placement is half the sound
Where you point the mic matters as much as which mic you use.
- Start at the 12th–14th fret, about 15–30 cm away, angled slightly toward the body. This gives a balanced tone.
- Avoid pointing straight at the soundhole — it’s boomy and bass-heavy.
- For stereo, use a matched pair in X/Y at the 12th fret, or one mic at the neck and one at the bridge/body for a wide image.
- Treat the room so reflections don’t muddy the recording — see acoustic treatment for home studios.
Common mistakes to avoid
Most disappointing acoustic recordings come down to a handful of repeat offenders rather than the microphone itself.
- Aiming at the soundhole: It is the loudest, boomiest part of the guitar. Pointing a mic straight at it floods the recording with low-mid mud that is hard to fix afterwards.
- Recording too close: Getting within a few centimetres exaggerates pick noise, finger squeaks and proximity bass. Backing off to a sensible distance lets the whole instrument develop before it reaches the capsule.
- Ignoring the room: A great mic in a reflective, untreated room still captures slap and flutter. Even a few absorbent panels or a heavy blanket on a stand behind the mic helps.
- Over-bright strings: Brand-new strings can sound harsh on a condenser. If the top end is fizzy, play the strings in for a day or reach for a warmer mic rather than trying to EQ it out later.
- Phase problems with two mics: When you use a pair, check the combined sound in mono. If the body disappears or sounds thin, the mics are fighting each other — move one or flip its polarity.

Frequently asked questions
Small-diaphragm or large-diaphragm condenser for acoustic guitar?
Small-diaphragm condensers are the classic choice for accuracy and detailed transients. Large-diaphragm condensers add warmth and body, which can suit solo or intimate playing. Many engineers keep both and choose by song.
Can I record acoustic guitar with a dynamic mic?
You can, but dynamics generally miss the high-frequency detail and air that make acoustic guitar sparkle. A condenser is strongly recommended for natural results.
Where should I place the microphone on an acoustic guitar?
Aim around the 12th to 14th fret, roughly 15–30 cm away, rather than at the soundhole, which is too boomy. Adjust distance and angle to taste while listening on headphones.
Do I need two microphones to record acoustic guitar?
No. A single well-placed cardioid condenser is perfectly capable, and in a band mix it is often the better option because it sits more easily. A matched stereo pair is worth it mainly for solo or featured parts where a wide, spacious image adds to the recording.
