<!doctype html public "-//w3c//dtd html 4.0 transitional//en"> <html> Wellll...  Suppose you do that and the tuning problem still exists.  The customer will feel they've been had.  What do you do then? If the problem and solution are not immediately obvious, I need some history to go on before I know how to proceed.  Now if I know that a good tuner was there last March in the dead of winter, and now the piano sounds terrible and is also very sharp, and worst in the tenor, then I have a history of sorts, and I can feel confident that a DC system will solve the problem.  Otherwise, that's a pretty risky place to start, don't you think?
