[pianotech] Another Cruise Ship Piano Tuning Question

[Edward Steltzer]

Most of us have probably seen a bit of that.  My experience has been that in 
the treble in some cases the strings on the lower row of pins may be off in 
the opposite sense from the upper row.

I think it may be due to the different length of string from the respective 
pin to the pressure bar.
