Methodology

Please note this shootout was not scientific. It was more representative of how I'd choose the appropriate mic for an instrument in an average session. For super scientific shootouts I would suggest 3D Audio.

Two small diaphragm condenser mics were used to record a Lowden acoustic guitar. In alphabetical order they were a Mercenary Audio KM69 and a Nuemann KM184.

Both mics were recorded at one time to ensure consistency and avoid variation between takes. The mics were positioned pointing at the sound hole at an approximate distance of six inches.

Both microphones were connected to A-Designs P1s with the gains matched by eye. A/D conversion was courtesy of an Apogee Rosetta 200 internally clocked. The files were recorded to Logic Pro with no additional processing.

Files were then bounced as 24bit Wavs. No eq, compression or reverb was applied.

Kev Bent at Unity Audio supplied the KM69 and the Nuemann 184 is mine.

Hope these files are useful.
