I don't know why you're so determined to keep pounding on "cheap". If they cost $50K each, and were made from hand polished titanium, the termination would still be whatever was chosen as an insert, and it would still be held down by a screw. I really don't see where cheap is so detrimental, or even a factor. As you said above, the stamped part isn't that important from a tonal point of view, and there's no reason for a cheap stamped part to be necessarily non-functional, or even inferior. Ron N
