When using this mic you will notice the midrange is flat and uncolored. With the low-end you may perceive a roll-off, but really everything is reduced evenly like a shelf filter. The response remains flat all the way to the lowest frequency of 40 Hz.
Simply said, the ATM450 is a very versatile mic that will work nicely in a variety of sources. It offers great value and is made by one of the most respected names in the industry.
5. Mojave Audio MA-200
Remember the Royer R-121? Well, it turns out that its maker, David Roger, also started a custom mic shop named Mojave Audio.
This was years before Royer Labs opened, back when David designed and built custom vacuum tube condenser microphones for engineers working at the big recording studios in Los Angeles. That is the heritage that the MA-200 has, making it one of the best microphones for recording acoustic guitar, and much more.
The MA-200 is the culmination of Royer's 20-plus years of custom microphone design. The large-diaphragm MA-200 gives warm, full-bodied reproductions of vocals and instruments without the shrillness and high-frequency grunge so often encountered with modern condenser microphones.

Need a microphone to record percussion, cymbals or brass instruments? The KM 184 is capable of handling high sound pressure levels with ease - as high as 138dB before overloading. But it's also extremely quiet, making it an excellent choice for capturing the subtle nuances of acoustic guitars and orchestral instruments.
Exceptionally high overload capacity (up to 138dB SPL before overload)
Exceptionally clear sound reproduction free of coloration
The Neumann KM 184 is a pencil-style small-diaphragm condenser microphone that can match the sensitivity of large-diaphragm microphones and still manage high sound pressure levels.
It features a frequency range of 20Hz to 20kHz, which is comparable to large diaphragm mics. Neumann emphasizes its minimal off-axis coloration; a great feature for recording acoustic guitars with a matched pair in an x-y or near-coincident formation.
Like anything Neumman builds, this mic features superior build quality and feel. High input gain is no problem with its supremely quiet operation.
This mic is renowned for working well with acoustic guitars, especially with stereo miking techniques. It has also developed a reputation as a great microphone for orchestral instruments, hi-hats, cymbals, and even vocal choirs.
Neumann has built something really special for stereo recording with the KM 184. Its phase integrity and tolerance are its best selling points, meaning you’re less likely to run into phase issues when mixing.
Some engineers claim that the Neumann KM184 is the best pencil-style condenser microphone, and to be honest, it is hard to disagree. This mic is just sensational.
Recording acoustic guitars is a beautiful art that is easy with the right tools. While you can still get a good recording out of a standard SM57 mic, it’s worth investing in a nice condenser or ribbon mic for a bit of extra character.
All the microphones on the list above are some of the best and most renowned in the industry at their price point. Many of these mics are also versatile enough to work well on other instruments as well, like vocals and guitar amps.
