I had a drum session today, so we put up all four of ADK's FET AU II series mics to test them!
I've been lucky enough to have a pre-release version of the Cremona and Berlin, as well as the Hamburg II and the Vienna II here at my studio for a bit to evaluate them. The FET mics were all placed in a fan above the rack tom about 6.5 feet off the ground, with the diaphrams as close together as I could manage.
There is a tiny variation in th directionality but not more than a few degrees. They were all set to the same level on a different channel of my ISA 428 on medium impedance.
