rusted piano strings

[Greg Newell]

Don,
	Once again we agree. I like the systems and install my fair share of
them. I just have difficulty with the pages of the brochure that tout help
with grand sticking keys and sluggish hammers. I am not convinced that the
units help in these areas. I'm also troubled by the drawn pictures of a
grand pin block and rusty strings. If a string cover is used these two items
could possibly be affected, as you've said, over the long term.

Hi Greg,

There is some benefit to a grand DC system without the covers. It's much
better to use them, and I will no longer install a system without the
bottom cover.
