Jerry Bruck called me yesterday to say he heard from SD that these have just started shipping, I should have mine Friday or next week.
I can't imagine anyone wanting to tape a piano from behind the pianist. When I've had to sit in that location, the acoustic is unacceptable. When a pianist conducts from the piano and has it turned so he can face the orchestra, with the keyboard out to the audience, the result is beyond dreadful, even with louvres over the soundboard to try to project the sound out. I've never seen anyone try to mic a piano there.
