• Body Resonance: The guitar’s body resonates, affecting the instrument’s overall tone.
• Air Resonance: The air inside the guitar body enhances projection and sustain, especially in the lower registers.
• Soundhole Position: Miking directly in front of the soundhole can result in a ‘boomy’ sound due to exaggerated air resonance.
• String Sound: The strings produce a brighter, more direct sound that becomes more prominent as you move the microphone away from the soundhole.
• Pick/Fret Noise: These mechanical noises are more pronounced at close range and can be minimized by adjusting microphone distance.

4. What Are Some Common Acoustic Guitar Microphone Positions?

Finding the perfect microphone position is a crucial step in capturing a great acoustic guitar sound. The positions allow you to experiment to find the ideal spot for your recording needs. Working engineers often recommend specific positions, each with its unique characteristics.

• Vanilla Position: Point the microphone at the junction of the neck and body for a balanced sound.
• Front Position: Place the microphone in front of the guitar’s body, off-axis to the soundhole, to capture a more natural tone.
• Bridge Position: Position the microphone near the bridge to reduce string emphasis and capture more body resonance.
• Player’s Ear Position: Place the microphone near the player’s ear to capture the sound they hear, being mindful of potential shadowing effects.

Mike's 'vanilla position' is to place the mic pointing somewhere around the area where the neck joins the body. The precise angle of the mic and distance from the guitar will vary according to the guitar, the track and the desired sound.

5. How Does Microphone Distance Affect Acoustic Guitar Recordings?

Microphone distance greatly impacts the balance between the guitar’s direct sound and the room’s ambience. The choice of mic distance can drastically alter the character of the recording, with various engineers having different preferences. Finding the right distance is crucial for achieving the desired sound.

• Close Miking: Captures more detail and direct sound but can exaggerate proximity effect and specific regions of the guitar.
• Distant Miking: Captures more room ambience and a more holistic sound but can sacrifice immediacy and clarity.
• Engineer Preferences: Some engineers prefer close miking (a few inches), while others prefer distances of two to three feet.
• Compromise: Striking a balance between capturing the instrument’s sonic contributions and minimizing unwanted room ambience is key.

6. What Role Do Microphone Polar Patterns Play in Recording Acoustic Guitar?

Microphone polar patterns determine the directionality of the microphone’s sensitivity, affecting how it picks up sound from different angles. Understanding and utilizing different polar patterns can help tailor the recording to the specific needs of the guitar and the recording environment.

• Cardioid: This pattern picks up sound primarily from the front while rejecting sound from the rear. It’s useful for reducing room noise but can sound unnatural up close.
• Omnidirectional: This pattern picks up sound equally from all directions. It provides a fuller picture of the guitar and avoids proximity effect but captures more room ambience.
• Figure-8: This pattern picks up sound from the front and rear while rejecting sound from the sides. It can be used in stereo miking techniques.
• Keith Olsen’s Recommendation: Olsen recommends using an omnidirectional polar pattern for acoustic guitar recordings.
• Proximity Effect: Directional mics used close up can unnaturally spotlight specific regions of the guitar and exaggerate low-end frequencies.

7. How Does the Recording Environment Impact Acoustic Guitar Sound?

The acoustics of the recording environment profoundly affect the overall sound of the acoustic guitar. The choice between a live or dead room can significantly impact the recording’s tone and flexibility in the mix.

• Dead Room: Recording in a highly damped environment allows for more flexibility in adding reverb and effects during mixdown.
