Rick Epping писал(а):The holes in the side of the Marine Band comb developed from the old Marine Band
cover design which had four little feet holding it up off the reedplate. The
idea was to allow the covers freedom to resonate sympathetically with the reeds,
thereby enriching the tone. Quoting from Jacob Hohner's patent of the Marine
Band cover: "This freedom of vibration is greatly extended by securing the
cover-plates at the ends by lugs or ears, which are separated from each other.
Thus, as will be readily understood, each cover-plate is held at only four
points by narrow lugs and, being without any ribs, ridges or corners, is
perfectly free to vibrate throughout its entire length and width, even down to
its line of contact with the reed-plate at the front." The original cover
design, while very resonant, was easily crushed and so was altered somewhat to
add strength, I think sometime in the 1930s; the sides remained open as much as
possible. Also on the subject of cover resonance, the original MS covers were
0.5mm thick, but we found that they were not as resonant as the thinner (0.35mm)
covers of the old style Marine Band and other 10-holes, so we switched to the
0.35mm material for MS. Big River Harps may still have 0.5mm covers.
