Perhaps so... but then I guess that means that Yamahas, Kawaiis, Young Changs,
Samicks... etc etc etc ad absurdum dont have that trick figured out. One of my
biggest beefs with plate bushings is that they just dont stay put. The only
plate bushings I ever did see that did were not made of wood, but rather some
kind of rubberish stuff... Knight uprights. Didnt really like the feel of the
tuning pins in those however... the just felt a bit gummy when turning.... hard
to get a feel for the right pin set.

Cant say as I've had much experience with Kimsballs tho... we dont see them
often over here.
