Titolo: John Suhr e il mistero delle camere tonali...

Dopo la discussione sul "brevetto" o sul presupposto "modo particolare
di scavare le camere tonali"...ecco la risposta definitiva : quella di
John (posto con la sua autorizzazione) alla mia domanda:
I certainly have no "Patent" for my method of chambering
What I did is cut and built 10 guitars each of S and T body styles
with
different methods of chambering.
Each of these guitars had identical specs as close as I could possibly
make.
I then used my ears to determine the one that retained as much fatness
as I
could get but add the character of chambering. Certainly some methods
didn't
add any character but lightened the guitars up a little, some sounded
like
arse.
The whole idea of finding a resonant frequency and the repercussions
of it
are a grey area to even some of the best Arch top builders I have had
discussion with.
So I go for what sounds good to my ears
I did just order a $15,000 Audio test station with FFT spectrum
analysis.
I'm not the kind of person to leave well enough alone and I will
certainly
experiment with the possibility of finding some way to "drive" a body
and
neck to see what the connection of resonant frequency is to tone,
sustain,
and playability.  
However it will be a long road since the factors that determine this
are
many and include tuning gears bridges and every single piece of
hardware or
plastic that is added will change the interaction.
I even remember "tap tuning" 10 neck blanks all the same dimension
before
the necks were cut. I marked down the frequency high, medium, low.
After cutting the necks all identical same shape, fingerboard etc, the
frequencies moved, some low went to high etc.
So there are quite a lot of issues involve when dealing with an
inconsistent
density material such as wood.
It will be fun some day to figure out a way to measure things and
qualify a
neck to a body but I think at this time anyone saying they have it
nailed is
not being truthful.
Kind of like that Fender book or add where they had a guy (Oscar who
used to
strip bodies with paint problems, not a builder at all) holding a
tuning
fork to a guitar body as if he was looking for something. I have NEVER
seen
anyone do that while I worked there and that wasn't his job anyway.
Pure
propaganda! LOL

Fai chitarre? :|

 propaganda! LOL
tipo uno foto nel libro della Fender dove hanno fotografato un tizio
che non era neanche un liutaio ma l'adetto alla sverniciatura che stava
colpendo dei pezzi di legno con un diapason.
pura propaganda.

Dona', ti ringrazio moltissimo, sei stato gentilissimo. Ero un po' di 
corsa e non riuscivo a leggermi tutto il testo.
