[CAUT] RE : huge pitch raise question

[Jim Busby]

Ditto Marcel,

Maybe my post didn't come through to you Michelle, but what was the
piano (make)? That could make all the difference in the world as to the
"why". I had several Young Chang "Bergman's" about 12 years ago that all
had the same problem you mentioned. Maybe the stringers actually created
the problem. 

Thanks.

Hello Michelle,

I just did a chinese import this afternoon. The piano had been delivered
in the crate last may. There were still some kind of paper pattern stuck
to the bass struts and the paper was touching some bass strings. WOW,
what a sound.

Now I would like to ask you if the string breakage you experience is
with these chinese imports. The reason I ask is that this particular
piano scared me. The first tenor strings had so much angle up from the
V-bar that they just didn't want to move. I thought of your post and I
had a lot of cranking up before the pitch actually started to change. I
didn't measure the angle, but it looked like 30 or more degrees.

I was lucky, nothing broke but the piano was a beast to bring back to
pitch and tune. The pins were tight and springy. Not fun but the pay is
good. But it upsets me that some store send pianos in crates with NO
PREPARATION whatsoever.
