Are there anything to these?  I know similar style mics can have quite nice elements inside...or so I'm told.

Hi - I am not familiar with

Hi - I am not familiar with the mic - at least, not without a picture. I can tell you that the term "controlled reuctance" was coined by Shure, and it is likely that this mic has a Shure CR element in it. That is a great element! But depending on the mic it might be high, medium or low impedance - High- and low can be easily made to work for harp mics but medium is a little more problematic. With an impedance matching transformer they tend to be too hot; without one - too weak.
