acoustic guitar application - everything i hoped for
Setting up a home studio and decided it was time to take a plunge and see if mics like this really were worth the cost. really does a great job on my acoustic guitar I'm running it through a WARM preamp sounds fantastic
by Sweetwater Customer on
A Staple for Acoustic
I've got about four months experience with these. I liked the first one enough that I bought a second (although lately I favor pairing it with a ribbon). It's always one of my first grabs for acoustic guitar. A lot of times, I don't even go to anything else. When I shoot it out vs my other SDCs and LDCs it almost always stays in the mix. When I want something bright, clean, and pleasant this Is the one. I like it best about 18" away from the guitar directly in front of the 7-9th fret pointed towards the neck/body joint.

Love on Acoustic Guitar
I have a lot of mics to choose from. Take the price and name of all of them and this is my favorite mic on acoustic guitar now. I'm tracking as I type and it just sounds great. Like another review I wish I had bought more

What was missing
this mic....wow...why didn't I buy a stereo pair. Is my only regret.
If you are recording or micing acoustic guitar, this is it
.stop wasting money buying anything else,!!!

Excellent for acoustic guitar
Purchased and received a pair of these a few days ago. Implemented these immediately in my home studio and these capture the nuances of an older martin guitar beautifully. Very pleased.

What Do Our In-house Gear Experts Think?
Jeff Barnett
A classic. The KM 184 is a standard fixture in any serious mic collection. It's the quintessential mic that other small-diaphragm microphones seek to emulate.
Paul Lea
Look no further if you are in search of a solid and reliably great sounding mic for your acoustic guitar. It also works great on classic "blackface" guitar amps.
Stuart Niven
The Neumann KM 184 is an essential microphone for any recording engineer's microphone cabinet. Simply wonderful on acoustic guitars with a very detailed and clear articulation. On cymbals it shines, bringing out the natural presence and shimmer, making you think that you are right there in the room as it was recorded! Wow! Pick up a pair of these and you have a killer pair of overhead microphones!
Kyle Manship
A first physical encounter of the KM 184 can be deceiving. It's a small and lightweight microphone, unlike its sound. Based on the legendary KM 84 from 30+ years ago, the KM184 continues the legacy of Neumann's professional and ear-pleasing products. Based on the same capsule design and size as the KM 84, the KM 184 is a perfect addition to any home or professional recording studio, as well as the touring musician. This microphone is renowned for drum overhead and hi-hat applications. The frequency response is flat and smooth. Despite being a +48V Phantom-powered tubeless microphone, it still retains tube warmth and fullness. It is detailed and clear across its frequency spectrum. Hearing this microphone for the first time on acoustic guitar just flat out blew me away. It sounded so huge and warm, yet accurate and detailed. It requires little to no EQ, even on a less than stellar instrument. As a stereo pair in an X/Y application on drum overheads, the KM 184 reproduces an outstanding stereo image and clarity to a drum set, capturing every nuance of the slightest crash and accent. The KM 184 is an outstanding upgrade at an even better price point for the home studio owner. This will definitely take your tracking and finished products up exponentially in quality. The KM 184 is a standard in all professional recording studios and is a must for any audiophile.
