Recording Acoustic Guitar – A Comprehensive Guide

Recording Acoustic Guitar – A Comprehensive Guide – Ah, the acoustic guitar—the sweet-sounding serenader of souls and the ever-faithful companion of countless campfire jams and heartfelt sing-alongs. But before you embark on your sonic adventure, there’s a secret to unlock: the elusive art of microphone placement! Fear not! We’re about to delve into a journey that will lead you to the hallowed grounds of capturing untold beauty and warmth from the acoustic guitar in every recording. So, tune your strings and pay attention—you’ll soon discover how to make your guitar go, “Wow, they really get me!”

1. Selecting the Right Microphone

Before we dive into placement techniques, let’s discuss the three main types of microphones commonly used for recording acoustic guitars:

Condenser Microphones: These are the most common choice for recording acoustic guitars. Why? Because they’re sensitive and capture a broad frequency range. Condenser mics deliver a full-bodied sound with a strong low-end, detailed mid-range, and sparkling highs. They excel at capturing the natural nuances of the instrument. Keep in mind that they also pick up more room ambience, which can be either a pro or a con depending on the recording situation. Popular large-diaphragm condenser mics include the Rode NT1000.
Dynamic Microphones: While less sensitive, dynamic mics offer a tight, focused sound with minimal room ambience. They’re great for genres like pop or rock, where the guitar track needs to fit into a busy mix. The Shure SM57 is a popular dynamic microphone for recording instruments, including acoustic guitars.
Ribbon Microphones: These are very sensitive and capture a warm, full sound. Ribbon mics have a natural roll-off in the high end, which gently reduces excessive brightness while maintaining clarity. Handle them with care, though—they’re delicate and tend to be more expensive than dynamic and condenser mics.

2. Single vs. Dual Microphone Setup

Now that you’ve chosen your microphone, let’s decide whether to record with one or two mics:

Single Mic Setup: If you’re aiming for simplicity, a single mic can work wonders. Position it carefully to capture the sweet spot of your guitar. More on that below!
Dual Mic Setup: For added versatility and tonal options, consider using two microphones. Here are two popular stereo recording techniques:
- A/B Stereo Recording: Place two small-diaphragm condenser mics parallel to each other at different points on your guitar. This technique captures a wide stereo image and works well for spacious, natural recordings.
- X/Y Stereo Recording: In this method, two mics are positioned close together, forming an “X” or “Y” shape. Aim them at the 12th fret, about a foot away. Avoid pointing directly at the sound hole to prevent excessive boominess. X/Y recording provides a focused stereo image.

3. Finding the Sweet Spot

Now, the crucial part: microphone placement. Here’s a step-by-step guide:

Positioning for Solo Guitar:
- Place the mic around 12 inches away from the guitar.
- Aim it at the 12th fret (where the body meets the neck).
- Experiment by moving the mic slightly closer or farther to find the sweet spot that captures the warmth and resonance of your guitar.
Recording Fingerpicking or Strumming:
- For fingerpicking, move the mic closer to the soundhole (around 6-8 inches away).
- For strumming, position it slightly farther back (around 12-18 inches).
Avoiding Plosives and Boominess:
- Angle the mic slightly downward to minimize plosive sounds (like “p” and “b”).
- Experiment with angling to find the right balance between body and clarity.
Room Ambience:
- If you want more room sound, move the mic farther away.
- For a dry, intimate sound, keep it closer.

Remember, there’s no one-size-fits-all approach. Trust your ears, experiment, and adapt to your specific guitar, room, and musical context. Happy recording!
