Made for www.recording-engineers.com - Upcoming Audio recording forum. We decided to compare ther Shure SM57 and 58 microphones on acoustic guitar. We made the test conditions as fair as possible and no EQ, compression or other effects were added. The same gain levels were used and the same microphone positions were utilised. The clips are (in order): -SM57 directly in front of the sound hole (0:19) -Sm58 directly in front of the sound hole (0:49) -SM57 in front of the sound hole with SM58 on pointed at the 8th fret of the neck, the levels were adjusted to make them equal in volume. (1:19) -SM58 in front of the sound hole with SM57 on pointed at the 8th fret of the neck, the levels were adjusted to make them equal in volume. (1:49) We personally preferred the last recording as it produced a more full tone with a nice top end sparkle. The others all sounded a little thin, dry and generally less pleasing. With a little bit of time spent adjusting the microphone positions, adding some reverb, EQ and and a better guitar, we think that that it could be turned into a very pleasurable sounding guitar tone. The guitar used was a cheap, £50 Falcon FG100N acoustic guitar It's worth noting that the internals of these microphones are identicle, the shape is slightly different but the real difference lies in the grills. Either microphone can be made to sound similar to the other, regardless we thought it'd be a useful comparison for first time microphone buyers. Cheers for watching <b>...</b>
