I'm very curious how this mic, and the 40 do on acoustic instruments.
Russ Long, according to his review, preferred the 30 to the 40 on acoustic guitar.
I'm interested in capturing a detailed image of acoustic guitar, banjo, and fiddle while avoiding string/pick/bow noise.
The 30 has a 1 1/8" diaphragm while the 40 has a 1 1/2" diaphragm.
I'm thinking here that the larger diaphragm in the 40 might gloss-over a lot of the detail that acoustic instruments need (like SDC vs LDC on instruments).
