I tried many ways to make the accordion sound good and it seemed almost impossible, mainly the bass part.
As we have no bassplayer in the band, the accordion had to work also as a lead bass in the left hand, but this was the first time it really worked like it should. Very nice bass sound.
The melody part sound is also a nice surprise. Two microphones mean, that the ballance between octaves is perfect, you can hear it almost like it was accoustic sound of the instrument, I enjoyed it much.
The installation was like 10 minutes or less, one does not need to be an accordion specialist to install it properly.
A bigger challenge was finding the best place for the bass mic, one have to try more different places, as it depends on the type of the instrument.
And the best part was -> no feedback during the concert, I was more then 5 decibels bellow the feedback point in ff (fortissimo), so absolutely no stress at all, one can concentrate only on music.
All I can say is, the producers of this product knew what and how they did and they did well.
