Beyerdynamic MC-930 Stereo Set provides a great pair of microphones for stereo recording of acoustic guitars (I believe there are a number of other possible applications, like overheads, choir recording, orchestra recording,... but I need them primarily for recording acoustic guitar in stereo).
Mics are extremely sturdy, really excellent build quality. They have two switches, one for -15dB pad and another for 250Hz low-cut filter. The later is quite uesful for stripping off the 'boomy' frequencies when recording guitars,... I connect both mics with low-cut filter to my Apogee Duet and through that I can get guitar tracks which need almost no post processing. The recorded sound is excellent,... well, probably there are other mics that to sharp ears may sound better, but the response provided by Beyerdynamic MC-930, at their cost is, IMHO, impossible to beat.
Mics are delivered and can be stored when not in use in a secure box, along with shock mounts and foam wind shileds. I believe Beyerdynamic should include into this box also a "Stereo Bar", something like K&M 23550, for easier setup for XY stereo recording,... - funnily, there is a room for such bar in the fom inside the box, it is only that there was no bar supplied,... well, I just ordered it for a couple of Euros and now I am all set,.... and yes, that bar fits nicely in the Beyerdynamic MC-930 stereo Set box.
