One typical thing of the theorbo is the very powerful basses of the extra long strings. They are hard to capture with non-omnis. Listen to the following sample. It is recorded with an MK22/MK8 M-S combo as mains, a BLM3
boundary layer mic in front of the theorbo on the floor and an SF24
in the room for space. (The SF24
is the reason for the rather high noise level.) The MK22 is placed some two to three meters away from the singer, who plays the theorbo herself. The BLM3
is about one meter away, while the SF24
is four to five meters away and 2.5 meters up. It's a live recording. There is no frequency filtering in any of the tracks.
