I thought it was a different mic set of the same piano?
If so, is the difference in sound only due to the mics and position?
"Sister" is Worra-speak for "same piano, different mike setup"...he's previously used this terminology in the "White Grand - White Sister" combo.
Hence also the discount for TBO users, since it IS the same piano.
Yep, same piano, but different microphone placement and different mikes.
TBO was close, really close, using a Neumann SM2 stereo michrophone.
7CG was recorded using two vintage Neumann U89. These where placed over the soundboard, but further away then the SM2.
It gave the piano another character both from being further away and also from the sound of the U89
