Wapin Bridge

[Richard Moody]

Hi David,
    The best explanation is at www.wapin.com   or 1-800-835-4757
as given in the ad in the May Journal. p 9.  There (web site) you
will see a configuration of 3 bridge pins (across the length of
the string) instead of the universal staggered two.
I have tuned one wapinized piano and was impressed very much.  It
was an SnS M and the extreme treble was a dream, or like you
always dreamed a treble could be.
    The Wapin bridge pin configuration has a patent so there
should be details at the Patent Office.  Being patented you have
to pay a royalty to install it.

    However since most patents to  "improve the sound of the
piano" may vary with experience, much experience is needed with
the Wapin.  If the treble can be improved in all pianos like I
heard in the M then we will see a treble Wapin in all pianos in
the future. I am  contemplating trying it on my own grand piano
(Conover Cable 1920's) if they give approval and a break on rates
for partial conversions instead of full.
