Alan, thanks a bunch for your input. I am ordering the Eder viddy plus the Well Prepared Piano (I should, since my brother works at Colorado College). I have a request for further info into the manufacturer regarding the string breakage, but I am interested in investigating as per your advice. By the bye (or however that expression is spelled), I'm not clear on what procedure is needed to determine the scale. Mike the string and measure speaking length? How do you determine the tension? I'm fairly green in this subject, but eager to take it in.
