How to Record Acoustic Guitar at Home (Studio Guide)

Why Recording Acoustic at Home Sounds Bad by Default

A professional acoustic guitar recording is 30% microphone, 20% placement, and 50% room. Most home setups get the mic and placement right and then record in a small untreated bedroom that destroys the tone with early reflections off parallel walls. A $3,000 Martin D-28 recorded with a $500 condenser in a bad room sounds worse than a $400 Yamaha recorded in a proper space with a $120 mic. I measure this every week, the room is the single most expensive variable most home recorders ignore.

This guide covers the complete acoustic recording chain for a home setup on a realistic budget of $500-1,200. I recommend specific microphones, cover the two-mic technique I use for my own session work, and explain how to treat a bedroom into a usable recording space for about $200 in acoustic panels. By the end you will be tracking acoustic guitar that sounds competitive with mid-tier professional recordings.

Microphone Selection: Small Diaphragm Condenser First

A small-diaphragm condenser microphone is the correct default for acoustic guitar. Large-diaphragm condensers are designed for vocals, they color the tone in ways you don't want on a percussive transient instrument like acoustic. Small-diaphragm condensers (called "pencil" mics) capture the fast attack of a plucked string accurately and produce more natural high-frequency response.

For under $200, the Rode NT5 ($219 each, sometimes available as a matched pair for $399) is the entry-level standard. At the $300-500 range, a Shure SM81 or an AKG C451B give you session-grade recording capability. At $800-1,200 a pair of Neumann KM184s is the broadcast standard and will be the last microphones you ever buy for acoustic work. A single mic is fine for mono recording, two mics unlock stereo placement tricks that are worth learning.

The Two Mic Placements You Need to Know

Placement 1 (the 12th fret): Aim a small-diaphragm condenser at the 12th fret of the guitar, 12-14 inches away, slightly off-axis (pointing 5-10 degrees away from the soundhole). This is the single best placement for a balanced mono acoustic track. It captures string attack and finger articulation without the low-end boom of the soundhole or the thin high end of aiming at the bridge.

Placement 2 (the two-mic spread): Use the 12th fret mic as your primary, then add a second mic aimed at the bridge from behind the player's right shoulder, about 18 inches away. Blend the two 60/40 in favor of the 12th fret mic. This gives you depth, stereo width, and the best of the warm body tone plus the clean attack. The classic recording manual version of this is sometimes called the Bruce Swedien "X/Y pair", same principle, different geometry.

Room Treatment: The $200 Bedroom Fix

Your recording room doesn't need to be soundproof (which costs $5,000+). It needs to be acoustically treated, which means reducing the parallel-wall reflections that cause comb filtering and early reflections. Buy eight 2'x2' acoustic panels (Auralex, GIK Acoustics, or ATS Acoustics) for roughly $200 total. Hang two on each wall in a pattern that covers the reflection points.

The key spots are the walls directly to the left and right of your recording position, and the ceiling directly overhead. Cover each of these with at least one panel. If your bedroom has parallel walls, hang panels asymmetrically to break up the symmetry. Don't forget to put a rug under the recording chair, bare hardwood is one of the worst reflective surfaces for acoustic recording.

Audio Interface and Preamp

A basic two-input audio interface handles everything a home acoustic recording needs. The Focusrite Scarlett 2i2 ($169-200) is the default entry-level choice, it has two mic preamps, phantom power for condenser mics, and converters that are transparent enough for professional work. The Universal Audio Volt 276 ($299) is the step up with slightly warmer preamps. Anything much more expensive than these is probably overkill for home acoustic work.

You do not need an outboard preamp for acoustic guitar recording in a home setup. The built-in preamps in a modern $200 interface are good enough that the next upgrade (outboard preamps, converters, etc.) costs thousands of dollars for small improvements. Save the money for better microphones and room treatment, which deliver much larger tone improvements per dollar.

The Complete Signal Chain

Guitar > small-diaphragm condenser mic (at 12th fret) > XLR cable > audio interface > USB > DAW. That is the entire chain. A DAW like Reaper ($60 personal license), Logic Pro ($199 Mac only), or Ableton Live ($99 intro version) handles recording, editing, and mixing. For a first acoustic recording session, avoid adding plugins, effects, or processing during tracking, record dry and add reverb, EQ, and compression only in the mixing stage.

Set your interface gain so that your loudest strummed notes peak at -6 dBFS, never red. The goal is clean signal with headroom, not maximum volume. Modern digital recording doesn't benefit from hitting close to 0 dBFS the way analog tape did, and clipping the converter is the single worst sound in home recording. A -12 to -6 dBFS peak target is what professional studios use.

Five Home Recording Mistakes

Mistake 1: Using a large-diaphragm condenser as the primary mic. Switch to a small-diaphragm condenser for acoustic. Mistake 2: Recording in a small untreated bedroom with parallel walls. Hang panels or move to a larger room. Mistake 3: Putting the mic at the soundhole. Move it to the 12th fret for dramatically better tone. Mistake 4: Too much gain, clipping the converter. Aim for -12 to -6 dBFS peaks, never red. Mistake 5: Processing during tracking. Record dry and add effects at the mix stage when you can undo them without re-recording.
