Broadwood Bass string

[Andrew and Rebeca Anderson]

This discussion is noteworthy in that this problem has cropped up in 
rebuilding.

A rebuilder that I am aware of copies the scales in pianos that come 
to them without looking at the scale (usually) to see if it will 
work.  They have had problems where treble wires are breaking all 
over the place when trying to get them up to pitch or worse, shortly 
after delivery   Now this can happen in bass strings too that are 
covered with a material other than copper and then a copper string 
clad string is substituted and you can't get it up to pitch without 
snapping it.
