We have matched this D112/c Superlux to the PSV. Why? because they are a great Harp mic without the huge cost and easily available. It fits into your hands nicely and looks the part on stage. It is a Hi-Z mic with a Volume knob and long cable to Jack attached.
The output frequencies and levels of this microphone are matched to the Psv to give you all that a harmonica can offer and some. Due to the matching between this mic and the PSV , Feedback is minimised dramatically but of course never deleted without some minor adjustments on the PSV/PA/Amp.
