Best Mics To Record Acoustic Instruments

Recording acoustics can be quite challenging. You need to understand the right type of mic to use and where it should be placed. Also, the placement of the mic should not affect the performance of the musician or even the band.

Which Mics To Consider To Record Acoustic Instruments?

Read this post to consider what type of microphone is right for you to record acoustic instruments.

Condenser Microphones

Two types of condenser microphones can be used to record acoustic instruments:

– Small diaphragm microphones
– Large diaphragm microphones

Many recording studios prefer to use large diaphragm microphones for recording vocals because of their ability to capture everything. As the name suggests, large diaphragm microphones feature a large capsule measuring between one and a half inches and two inches across.

By using large diaphragm microphones, you can not only capture the sound of the acoustic instruments but also of the room you are recording in (Also, consider to read how to improve room acoustics).  This is one of the best ways to capture 3D sound.

You do not need to place multiple large diaphragm microphones on an acoustic instrument. Put the mic two to three feet away from the acoustic instrument, and it will capture everything. For instance, using a large diaphragm mic to record an acoustic guitar allows you to capture the entire sound of the instrument, including sounds coming from the bridge, soundboard, and strings.

The major drawback of large diaphragm microphones is that they are more sensitive to vocals. Therefore, it is challenging to capture acoustics with the microphone if someone is singing at the same time. The mic will capture more of the vocals than the instrument.

On the other hand, small diaphragm microphones or pencil microphones are designed to provide sound isolation. These microphones are typically very thin and can be as long as a foot long. A considerable advantage of small diaphragm microphones is they provide more focused sound. Therefore, they are beneficial when you want to isolate sounds in an environment with multiple sound sources.

Small diaphragm microphones are popular in movie sets because they provide exceptional sound clarity and reject noise from other sources. They can be quite useful when you need to capture sound simultaneously from an acoustic instrument as well as vocals from a singer. Small diaphragm microphones are incredibly useful for recording multiple sound sources than large diaphragm microphones.

2. MXL 990

If you are looking for a good microphone for a hobby, then the MXL 990 can make an excellent choice. Although this microphone does not provide amazing sound quality, it provides room for making modifications. The sound quality that this microphone captures is a lot like that of the TLM 103, which wouldn’t cost as much if it wasn’t for its Neumann badge.

The MXL, including its capsule, costs less than $300 even though it sounds more like a $1000 mic. If you are on a budget and are looking for quality microphones for recording acoustic instruments, the MXL can sound great once it has been modded.

3. WA-87

Based on the extremely popular Neumann U87, the WA-87 is one of the most sought-after microphones for recording acoustic instruments. Many leading artists have used this mic to record some of their best hits and for a good reason. Unlike the Neumann U87 that may cost upwards of $2000, the WA-87 costs less than $1000.

Some engineers have compared the recordings of the Neumann U87 and the WA87 and claim to notice a difference in sound quality. However, if you take two U87s and compared their recordings, you may notice a difference. The difference does not mean that one is better or inferior to the other. The fact is that the WA 87 can provide better quality recordings than microphones two or three times its price.

Apart from the excellent audio recordings, the WA 87 has many other useful features, including shock mounts and convenient wooden storage. You can always get it right with this microphone. For starters, this mic does not limit you to recording acoustic instruments only; it can also record vocals and other audio sources.

The major drawback of the WA 87 is that it is a large diaphragm microphone. Therefore, it needs to be a few feet away from the audio source to provide an excellent recording. This can be a significant disadvantage if you need to record both the acoustic instrument and vocals simultaneously and be able to isolate the sound sources during editing.

The inability to isolate sound is not a problem that is exclusive to the WA 87. Most large diaphragm microphones present problems when it comes to isolating sound sources in a recording.
