POW Maxwell's Silver Hammer, March 1992.
I openned.. an issue of Acoustical Guitar and there
in black and white, the printed words: THE LOST MOUNTAIN
CENTER FOR THE GUITAR.
A Kasha Design Master
Class with Richard Schneider. Needless to say I immediately
enrolled and was accepted..that in itself a minor
miracle since my lutherie experience was near nil.
The Lost Mountain Seminar Workshop introduced me to
an amazing new world which has now become part of
my life. From that experience with Richard Schneider
I dove headfirst and have been using the KASHA/ SCHNEIDER
designed bracing systems in my guitars and ukuleles.
So what is this system
all about? A collaboration between physicist Dr. Michael
Kasha and the late master luthier Richard Schneider..imparting
their theories and explanations of sound transmission,
plate vibrations, and tonebar placements to produce
a better guitar. A thirty year journey to create a
blueprint for guitar construction that took a different
approach to soundboard construction from the more
popular and prevalent fan bracings emmanating from
the Antonio Torres Jurado School; a creation of a
new soundboard design.
design..created a bracing pattern spreading out radially
from the bridge..a bracing pattern adjusted in lengths
and thicknesses! Kasha's tone bars are shaped and
positioned to follow the nodal lines of normal sound
modes in order to transmit impulses that the strings
create. The string vibrations are transferred to the
bridge and couples with the vibrating soundboard.
Kasha's radial patterns are placed so that their positions
will not interfere with the amptitude of sound wave
resonances as they develop into patterns.In essence
the Kasha/Schneider system is a graded asymmetrical
pattern with longer low frequency coupling bars on
the bass side of the bridge; graduating to shorter
high frequency bars on the treble side. The Kasha
bridge is designed with a wide bass side and a narrower
treble side to enhance the coupling between two occillators..the
vibrating strings...and the vibrating soundboard...coupled
though the back and forth and rocking movements of
the bridge. For a more thorough explanation see the
