RE: [Harp-L] re:What Cover-Plates Don't Do

I've had a number of different types of covers powder coated and it doesn't
seem (to my admittedly aging ears!) to make any difference to the sound or
timbre!  But they look great!

I doubt the coating would have any affect.  There is certainly no good
acoustic reason it would, and unless testing shows it then there is no
reason I can see it would make any difference.

The ones Vern conducted, yes.

Agreed, but a bellows which provides constant pressure or suction would be
significantly better than the tester.
