Hex wire

[Jim Coleman, Sr.]

Hi Dave:

There have been several pianos over the years which have used hex core
thoughout the bass section. A notable good example is the Fazer (Fahtzer)
piano made in Europe. I have seen 7'4 Grotrian Steinweg pianos with hex 
core. Nice sound. In the 50's Gulbransen made 6' grands with hex core bass.
