Hi Robin, It was basically a 1/8 inch steel "sandwich". I serviced one for a number of years and the hitch pins had begun to twist. I'm usually an A440 tuner on any first visit--except fot the Currier Strataphonic. The sound board was right up thru the pin block on these. It was a very innovative idea probably with insufficient execution and testing. The first one I saw was at a convention--and tuners were complaining they could not hear the "beats". I could--and saw no difference in the relative loudness of them. At 09:55 AM 8/28/02 -0700, you wrote: >What is the Currier Strataphonic String Panel?
