Ken,

The piano in question does not have the brass rods, but something else.

It was my experience that the brass rods decreased the friction at the capo
bar compared with the iron. This has been also been researched to some
degree - brass and steel are a naturally self-lubricating combination. This
one of the two arguments for using brass rods in the capo, or brass
half-rounds for counter-bearing string rests.

The other reason for using the brass rods in the capo is it helps to
prevent mis-shapen capo bar screwups that can occur at the factory.

If you've had tuning trouble tuning the ones with brass rods, maybe
something else is occurring with time that I am not familiar with - perhaps
some kind of corrosion or something causing things to get sticky.
