Recording Acoustic Guitar

Recording Acoustic Guitar

Before you record anything put a new set of strings on your guitar. Use a high quality set of strings! Don’t use cheap inexpensive poorly made strings. I like Elixirs, but whatever your favorite strings happen to be, using them will give you a sound you will be happy with in your recordings. This will make a great improvement to the overall sound quality when recording acoustic guitar. Strings have a life expectancy. Newer strings will sound better on your recordings.

Skinny strings sound brighter than thicker strings. So if you’re looking for more midrange or bass in the tone of the acoustic use a heavier gage string.

A condenser microphone will always sound better than a dynamic microphone for acoustic guitars. A condenser microphone will also sound better than the built-in acoustic pickups. The condenser will capture higher frequencies that a dynamic microphones and your acoustic pickup will miss. Popular microphones for recording acoustic guitar include AKG 414, Neumann K84, AKG C1000, AKG C3000, Neumann K184, and Sony ECM 50.

Sometimes I have used 2 condenser microphones. On occasion I have used one condenser microphone and also plugged into the piezo pickup at the same time. I recorded two separate tracks while doing this. Then I use the volume and the pans to blend both signals together during the mix.


Microphone Placement

Here is one way I have used two condenser microphones in the past. One was place towards the top of the guitar body and set on an angle looking down the body. It was pointed at the Sound hole. The other mic was placed on the opposite side of the sound hole. It was aimed toward the sound hole and the neck.

So as you can see there are many ways to place the microphone. There are many microphones to choose from to make your recording. That is what makes this an art form. Equalization begins from micing the instrument. That is why microphone selection and placement is so important.

acoustic 3Microphone placement is very important. Every acoustic guitar has something called the sweet spot. This is the spot that sounds the best and is the ideal place to put the mic. So look for it when you place your microphone. I have found that in most cases the sweet spot for acoustic guitar is between the sound hole and the neck of the guitar with the microphone angled towards the sound hole. Move the microphone around until you find the sound you want. Get down on your knees and listen to different angles of the guitar.

Running the microphone through a hardware compressor/limiter will almost always improve the recorded guitar sound. Try using one. Use a real hardware compressor and save the software one for the mix.

Other Tips and Tricks

acoustic 2If your acoustic guitar player is a heavy breather the microphone will pick it up. Try making the guitar player wear a dust mask or a surgeon’s mask while playing. That will get rid of the breathing sound.

In some cases you will hear fret noise when the fingers glide across the strings. To limit this you can use an emery board and very slightly file the rough edges off the guitar player’s calluses. Once this is done the guitar player should wash his hands. This should limit the squeaking fret noise that occurs from finger style guitar. Be very careful when doing this. A very light sanding is all that is needed.
Using all these tricks will give you better acoustic tracks.
