[pianotech] Drilled capo bars

[David Love]

I would think that would be counterproductive.  Think of the Bosendorfer
capo which is massive and helps to reduce energy loss from the speaking
length by virtue of that added mass.  Allowing the capo to vibrate more
easily would just bleed off energy from the string faster.  I don't get it.

Never heard of it. What manufacturers? What's the source of this?
