I have a customer with a 9-foot Baldwin D in his living room. I think this model is perhaps the predecessor to the later SD-10 (is that correct?). It is equipped with the not-common forward string termination inserts (under the capo bar) in the two treble sections that Baldwin used for a while (picture below).
I'll try to describe the unusual tuning pin movement I encountered. The two treble sections were about 2 to 5 cents flat. First I would drop the pitch a tiny bit to break any bond the string had made with metal is rests on and then bring the string up to my target pitch. Being that this Baldwin was not a Yamaha, I would bring the pitch just a cent or two sharp of my target pitch. Then, as is usual, I would attempt to lower the pitch down to target by reversing the rotation direction of my tuning lever. However, on many of the strings, when I make the movement to lower pitch, the pitch would actually go sharp about 5 cents! Holy cow-cookies, that really makes this little beast difficult to tune!!!
Anyone else had the same experience? Anyone care to venture an explanation?
Gosh I love tuning Yamahas. IMHO, they have the very best string rendering I have encountered.
Oh, and FWIW, this piano (probably 40 years old or so) has the most beautiful ivory keyboard. I was thinking as I was tuning it, that all those crusty old uprights that I've seen with their derelict keyboards, had beautiful ivory keytops 90+ years ago.......
