      Yes, I think so.  But how much?  I dunno.   I was not sticking to 
proven numbers, just general directions.  Bringing up a piano 25 cents from 
the middle or bottom will drop the top end, but I haven't seen the very top 
be too sensitive to the change.  I will admit to not measuring, so this will 
wait till my next major pitch raise, (which means, my next new customer...) 
   I will tune the C88 dead on before I do anything, and see where it goes 
during the raise.  
Thanks,
