The basic setup: one mic, positioned at the 12th fret
The simplest way to mic an acoustic guitar is to place a single microphone about 12 inches away from the guitar body, aimed at the 12th fret (the fret halfway down the neck). This position captures a balanced mix of the bass frequencies from the lower bout of the body and the treble from the upper bout and strings. For most recording and live situations, this single-mic approach works well and avoids phase problems that come from using multiple mics.
The distance matters more than you might think. Too close (within 4 inches) and you pick up finger noise and pick scrapes; too far (beyond 2 feet) and you lose clarity and pick up more room noise. Start at 12 inches and adjust based on what you hear in your headphones or monitor mix. Angle the mic slightly downward toward the body rather than pointing it straight at the strings—this reduces pick noise and wind sensitivity if you're playing live.
If you're recording indoors, the room itself becomes part of your sound. A treated room with soft furnishings absorbs reflections; a hard, empty room adds reverb. Neither is wrong, but knowing which you have helps you position the mic accordingly. In a live setting, keep the mic far enough from stage monitors that feedback doesn't become an issue.
Key Takeaways
- A single microphone placed 12 inches from the 12th fret captures a balanced acoustic guitar sound for most situations.
- Distance and angle matter: too close picks up finger and pick noise, too far loses clarity and picks up room sound.
- Condenser mics are more sensitive and capture detail; dynamic mics are more rugged and reject feedback better in live settings.
- If you use two mics, place them at least 3 feet apart or use a stereo technique to avoid phase cancellation that muddies the sound.
- Mic placement changes the tone: aim at the 12th fret for balance, higher on the body for more treble, lower for more bass.
Choosing between condenser and dynamic microphones
A condenser microphone is the standard choice for recording acoustic guitar because it's sensitive enough to capture the full range of frequencies and the subtle details—finger slides, string vibration, the attack of each note. Condensers need phantom power (usually 48 volts) from your audio interface or mixer, but most modern recording setups provide this. In a recording studio, a condenser gives you the most information to work with during mixing.
A dynamic microphone is tougher and rejects feedback better, which makes it the practical choice for live performance. It won't capture as much detail as a condenser, but it's less sensitive to stage noise, wind, and proximity to monitors. If you're playing outdoors or in a loud venue, a dynamic mic keeps your guitar sound clean without fighting feedback. The trade-off is that you lose some of the shimmer and nuance that a condenser captures.
For home recording, a budget condenser (in the $50–$150 range) outperforms a budget dynamic. For live use, a dynamic mic in the same price range is the better investment because durability and feedback rejection matter more than capturing every detail.
Two-mic techniques for stereo and depth
If you want a wider, more spacious sound, you can use two microphones—but placement is critical. The most common stereo technique is to place one mic at the 12th fret (as described above) and a second mic further back, aimed at the body from a distance of 2 to 3 feet. This second mic captures more of the room and the overall resonance of the guitar. Pan one mic left and one right in your mix to create width.
The danger with two mics is phase cancellation: if the two mics are too close together or at certain angles, their signals can interfere with each other, making the guitar sound thin or hollow. A straightforward rule: keep the mics at least 3 feet apart, or use the 3-to-1 rule (if one mic is 1 foot from the source, the other should be at least 3 feet away). Check your mix in mono to make sure both mics together don't create a weaker sound than one mic alone.
Another two-mic approach is to place both mics close to the body but aimed at different parts—one at the 12th fret, one at the sound hole. This gives you more control in the mix but requires careful phase alignment. Most home recordists find that one well-placed mic sounds better than two mics fighting each other, so start there before adding complexity.
Adjusting mic placement for different tones
The 12th fret position is a starting point, not a rule. Moving the mic up the body (toward the neck) brings out more treble and string definition; moving it down (toward the bridge) adds bass and body warmth. If your guitar sounds too thin, move the mic lower. If it sounds boomy or muddy, move it higher.
Aiming the mic at the sound hole directly gives you maximum bass and resonance but can sound boomy in a small room. Aiming it at the bridge gives you more attack and clarity. Aiming it at the neck gives you more string noise and finger detail. Experiment within a 6-inch range around the 12th fret to find what works for your guitar and your ears.
Distance also shapes tone: closer mics (6 to 8 inches) sound more intimate and pick up more detail; farther mics (18 to 24 inches) sound more spacious and natural. In a treated recording room, you can go closer without picking up too much room noise. In an untreated room or live setting, a bit more distance helps you avoid picking up unwanted reflections or stage noise.
Dealing with feedback and noise in live settings
Live acoustic guitar miking is different from recording because you're fighting feedback from stage monitors and ambient noise. Use a dynamic mic rather than a condenser—it's less sensitive and rejects off-axis sound better. Position the mic as close as practical (8 to 10 inches) without creating handling noise, and keep it away from monitor speakers.
If feedback happens, the first move is to reduce the mic level in your mix, not to turn up the monitor. A feedback loop usually means the mic is picking up its own amplified signal from a monitor. Move the mic farther from the monitor, angle it away from the monitor speaker, or ask your sound engineer to reduce the monitor level. If the guitar itself is feeding back through the amp, that's a different problem—it's usually a pickup or amplifier issue, not a mic issue.
Handling noise—bumps and rustles from the player moving—is common with live mics. A shock mount (a suspension system that isolates the mic from vibration) helps, but the best solution is a disciplined player who doesn't move the mic around during a song. If you're the player, find a comfortable position and stay there.
Microphone types and what they cost
| Mic Type | Best For | Typical Price Range | Key Advantage |
|---|---|---|---|
| Budget Condenser (Cardioid) | Home recording | $50–$150 | Captures detail and nuance |
| Mid-Range Condenser | Studio recording, some live use | $150–$500 | Better off-axis rejection, lower noise floor |
| Dynamic (Cardioid) | Live performance | $50–$200 | Rejects feedback, durable, handles high SPL |
| Ribbon Microphone | Studio recording (experienced users) | $200–$1000+ | Warm, natural tone; fragile |
You don't need an expensive microphone to get a good acoustic guitar sound. A $100 condenser mic placed correctly will sound better than a $1000 mic placed poorly. Spend your money on a decent audio interface and good monitoring headphones before upgrading the mic itself.
Recording setup: interface, cables, and phantom power
To record with a microphone, you need an audio interface—a device that converts the mic's analog signal into digital audio your computer can record. Entry-level interfaces (Focusrite Scarlett, Behringer U-Phoria, PreSonus AudioBox) cost $80–$150 and include phantom power for condenser mics. Connect the mic to the interface with an XLR cable (a three-pin balanced cable), plug the interface into your computer via USB, and open your recording software.
Use a balanced XLR cable, not an unbalanced instrument cable. Balanced cables reject electrical noise over long runs; unbalanced cables pick up hum and buzz. Even a 10-foot XLR cable is better than a 6-foot instrument cable for mic recording. If your cable is longer than 25 feet, you may need a preamp or active box to maintain signal quality.
Set your input level so the signal peaks around –6 dB on your interface's meter—loud enough to capture detail, but with headroom to avoid clipping if the player hits a string hard. Record a test take, listen back, and adjust. Most recording software lets you monitor the mic in real time through headphones so you can hear what you're capturing.
Frequently Asked Questions
Can I use a USB condenser mic instead of an XLR mic and interface?
Yes, USB condensers (like the Audio-Technica AT2020USB or Blue Yeti) plug directly into your computer and work fine for acoustic guitar recording. They're simpler to set up and cost less than buying a separate mic and interface. The trade-off is less flexibility—you can't swap mics or use the interface for other instruments later. For a first recording setup, a USB condenser is practical.
Should I use a pop filter with an acoustic guitar mic?
A pop filter is designed to reduce plosives (hard consonant sounds like "p" and "b") from vocals, not guitar. It's not necessary for acoustic guitar and can actually soften the sound slightly. Skip it unless you're recording both vocals and guitar through the same mic, in which case use a pop filter positioned between the vocalist and the mic, not between the mic and the guitar.
What if my guitar sounds too bassy when I mic it?
Move the mic higher on the body (toward the neck) or farther away from the sound hole. Bass frequencies are strongest near the sound hole and lower bout of the body. If the room itself is boomy, add soft furnishings (blankets, foam panels) to absorb low frequencies. In your recording software, you can also use an EQ to reduce bass, but fixing the mic placement first gives you a better starting point.
Do I need a shock mount for recording acoustic guitar?
A shock mount isolates the mic from vibrations transmitted through the mic stand, which can add rumble or handling noise. For recording, a shock mount is helpful but not essential—a sturdy stand and careful mic placement do most of the work. For live performance, a shock mount reduces the chance that bumping the stand will create noise in your mix.
Can I record acoustic guitar with a headset or lavalier mic?
Technically yes, but the sound will be thin and colored by the mic's design. Headset and lavalier mics are built for speech clarity, not music. They'll capture the guitar, but you'll lose the warmth and detail that a proper instrument mic provides. If you're in a pinch, it works; if you have any other option, use it instead.
