[pianotech] P-22 Bass Strings

[Susan Kline]

If you think recent P-22's are bad, just try some of the first P-202's!

There's a problem with the tuning pin and string angles -- the wire 
binds just
where is enters the coil. It wants to climb over itself. If they had 
been willing
to drill the holes at an angle, so the wire approached at 90 degrees to 
the tuning pins,
it wouldn't have happened.

The part I don't understand is why only one of the 8 is doing this, and not
the rest. Can you tell any difference between them? Are the serial 
numbers close
to each other?
