How to record acoustic guitar with a single microphone setup
Single-microphone recording is making a quiet comeback among bedroom producers in Adelaide, Sydney, and Perth, because it forces you to commit to a sound and a performance rather than fixing things later. There is something refreshing about the constraint. Without the option to layer takes or fix tuning in post, the focus shifts to the moment of playing, the room around the instrument, and the single point in space where the microphone sits.
For hobbyists working out of garages in suburban Brisbane or apartments in Melbourne's inner north, the appeal is simplicity. One microphone, one stand, one cable, and you are tracking. There is no multi-track juggling, no phase alignment headaches, just a player, an instrument, and a room. The approach also scales, since the same setup works for a singer-songwriter recording a demo, a classical player capturing a take for a recital, or a producer building the foundation of a folk track.
The technique teaches fundamentals that translate to larger sessions later. When you remove the option to overdub or layer, you have to get the take right the first time. That pressure, in the best sense of the word, sharpens your ear for tone, dynamics, and the small details of a performance. Many of the best records in any genre were tracked with very few microphones, and the discipline of working that way is worth learning even if you usually record with a full studio setup.
This article walks through the practical steps for capturing a clean, full acoustic guitar tone using a single microphone. It is written for members of the Melody Mix community who want to step away from the screen and into a more hands-on approach to recording.
Picking the right microphone for the job
Condensers are the standard choice for acoustic guitar because they capture the transient detail and the body of the instrument. Small-diaphragm condensers like the Rode NT5 or sE Electronics sE7 offer a focused, slightly bright character that flattens the percussive attack of the strings. Large-diaphragm condensers such as the Rode NT1 or the AKG C214 give a fuller, warmer picture and tend to sit a track nicely in a busy mix. It is worth noting that Rode is an Australian company based in Sydney, which makes their microphones a sensible local choice for producers concerned about warranty support and parts availability.
Dynamic microphones like the Shure SM57 are a different beast altogether. They are rugged, they reject bleed from loud sources, and they are cheap to replace if you drop one on a concrete floor while moving gear around a suburban garage. They do not have the high-end air of a condenser, but they can work beautifully for folk and Americana players who want a slightly compressed, mid-forward character. The SM57 has been a studio staple for decades, and it remains one of the best value microphones on the Australian market.
For most home recordists, a single small-diaphragm condenser is the safest starting point. The polar pattern is usually cardioid, which means it picks up the guitar in front of it and ignores most of the room behind it. This matters in Australian share houses and units where neighbours are close and ambient noise travels. In Brisbane's humid summers, condensers can also pick up moisture if stored carelessly, so a hard case with a silica gel packet is a worthwhile investment.
Treating the room without rebuilding it
No microphone will save a recording made in a bad room. Reflections, standing waves, and flutter echo muddy a clean signal before the preamp even sees it. The good news is that you do not need a professionally built studio to get a workable space. A few simple additions to a spare bedroom or a garage can make a surprising difference, and the results will outshine any expensive plug-in you might be tempted to buy instead.
In older Australian homes with high ceilings and timber floors, a few thick curtains, a rug, and a couple of moving blankets hung on the wall behind the player can tame the worst offenders. Brisbane's classic Queenslander houses, with their wide verandahs and tongue-and-groove boards, are gorgeous but they are acoustically live. Closing the internal doors, dropping a heavy curtain across the hallway, and placing the chair in front of a bookcase rather than a window will tighten the sound considerably without permanent modification.
In newer apartments around Melbourne and Sydney, you are usually fighting the opposite problem. Concrete slabs and plasterboard walls create dead zones that can make a guitar sound small and boxy. Adding a soft furnishing or two behind the player opens the sound back up without needing permanent fixtures. A bookshelf full of paperbacks, a heavy blanket draped over a stand, or even an open wardrobe full of clothes can do the job in a pinch.
Mic placement that works on the first try
The most reliable single-mic position for acoustic guitar is around the twelfth fret, pointing toward the joint between the neck and the body. From this spot, you get a balance of string detail and low-end body. Aiming the capsule straight at the soundhole from a foot away will produce a boomy, honking tone that no amount of equalisation will fix cleanly. Aiming at the bridge gives you a thin, brittle sound with lots of pick or finger noise.
Distance matters as much as angle. Start with the microphone about twenty to thirty centimetres from the guitar. Closer than that and you invite proximity effect, which thickens the bass and can overwhelm smaller-bodied instruments like a concert ukulele or a travel guitar. Further away and the room reasserts itself, which is fine if you are after that loose, singer-songwriter feel that suits tracks recorded in a Fremantle share house, but it is usually not what you want for a polished pop or country mix.
Try a small experiment when you set up. Record ten seconds, then sit down and listen. Move the microphone three centimetres toward the soundhole, record again. Move it three centimetres back toward the neck, record again. Within a few minutes you will have a clear sense of where your instrument lives in the room. The right spot will jump out of the speakers, and you will know it when you hear it.
Signal chain, preamps, and levels
Your microphone is only as good as the preamp behind it. Modern audio interfaces like the Focusrite Scarlett, Universal Audio Volt, or Apogee Duet have clean preamps that will faithfully pass whatever your microphone delivers. Higher-end units like the RME Babyface Pro or the Audient iD14 give a bit more headroom and a slightly sweeter top end, which matters when you are recording a performance rather than overdubbing a track later. Audient is a British brand, but their gear is widely stocked by Australian retailers and serviced locally.
Set your levels carefully. Aim for peaks around minus twelve decibels on the loudest strummed chord, leaving enough headroom to handle an unexpected loud section without clipping. In Australia, where mains voltage runs at 230 volts and many suburban homes have older wiring, a power conditioner is a worthwhile investment. It protects your interface from voltage spikes during summer storms that roll in across the ranges outside Canberra or along the coast, and it also cleans up the kind of buzz that older switchboards introduce into a recording chain.
Use a pop filter and a shock mount even for acoustic guitar. The filter reduces plosives if you are also capturing vocals at the same time, and the shock mount stops vibrations travelling up the mic stand. Both are small costs that pay off in the edit, and they extend the life of the microphone by keeping it stable during long sessions in your home studio.
Getting the take and committing to the performance
The hardest part of a single-microphone setup is not technical. It is the performance. With one chance to capture the guitar and any accompanying vocals, the player has to relax into the song and trust the setup. This is where a community of other producers becomes invaluable. Posting a rough take to a forum and asking for honest feedback teaches you more in a week than months of solo experimentation, and it gives you a reality check that is hard to get on your own.
When you set up to record, play the song through two or three times before hitting record. Use those passes to settle your hands, check your tuning, and get used to the headphone mix. Australian musicians are used to wearing headphones in hot summer studios, so a comfortable pair with breathable pads is worth the extra spend. A closed-back design like the Beyerdynamic DT 770 Pro will keep the click track out of the microphone and the room noise out of your ears.
One practical trick that experienced engineers swear by is the silent count. Before the take, count out loud "one, two, three, four" and then begin the song. The microphone picks up the count, and the editor can use the waveform to align the take to a grid or to a click track later. It is a small habit that saves real time in post, and it also gives the performer a moment to settle into the tempo of the song.
Beyond the technical setup, single-microphone recording is an exercise in trust. You are trusting the performer, the room, and the gear to deliver something usable in one pass. That same instinct for honest collaboration applies to online communities, where spotting the early signs of a conversation can save you from wasted hours and steer you toward collaborators who actually want to help. When you post a take for feedback, look for producers who describe what they hear, suggest specific changes, and respect the artistic choices you have already made. Those are the people worth keeping in your circle, and the practical move is to record your final take in one committed pass, then walk away from the screen for ten minutes before deciding whether the performance is finished.
