Ok, so I have been building an alternate tube U47 for awhile now, and I have finally finished! I may install a mod for a switch inside of the mic later on to achieve "true cardioid" (mine is a remote pattern selection mic like an M49), but as of now, as long as no problems arise, the mic is done. I decided to put it up against my Manley Reference Cardioid and do some tests on voice and acoustic guitar. I didn't spend much time on placement for the "best sound." I just set the mics up as close to each other as I could (somewhat difficult with LDCs), and went from there.

Feel free to guess which is which, or say which you prefer, or just compare the "quality." It's fairly easy to guess which is which is you know much about the circuit and capsule design of these two mics.
