942.1 | Materials mechanical properties | ELESYS::JASNIEWSKI | Ah, the road within without | Mon Oct 24 1988 12:39 | 28 |

Woods, like any other materials for building things out of,
have many mechanical properties. Different woods, of course, have
different properties, which can be made use of depending on what
you want for the behavior of a structure such as a guitar body.
Probably the most obvious property is density. Woods such as
"pine" arent very dense, whereas some of the more exotics like
"Brazillian rosewood" or "koa" are probably very dense. This density
is exploited to make a guitar body very heavy, giving better sustain,
for a given shape that can only contain so much material - like the
classic "strat" bodyshape.
A more subtle property is called "Q". It's a resonance quality
factor; wood on a marimba has a high "Q" and thus the bars "ring"
when you hit them. Well, guitar bodies also can ring, which I always
thought was a characteristic of Gibson instruments. However, it
is debatable whether you *want* your electric guitar's body to ring
or to be somewhat "dead" - in and of itself.
I suspect that by layering a number of different woods in the
construction of a guitar body, you can generate a structure that
has properties that cannot be obtained through the use of one single
wood type. For example, it is non resonant, sustains well but doesnt
weigh a ton, is also extremely strong and stiff, and has whatever
"finish" on top and in back that you want.

942.2 | 2c worth of wood | ANT::JACQUES | | Mon Oct 24 1988 15:19 | 39 |
| There are many woods suitable for making musical instruments.
The standards (Mahagony, maple, rosewood, ebony, spruce, cedar)
were selected for tonality as well is looks. They are all fine
grained woods. Heavily grained woods have never been used much
for making instruments. I guess the early luthiers ruled them
out either because of undesirable tones, looks, or construction
problems. I always wondered why you don't see oak instruments !!
As far as I know Fender used Ashe because it was growing in abundance
in California, and could be purchased cheap. Since Fender was setting
the style anyways, they chose to use an inexpensive wood that was
functional acceptable, and cover over it with opaque/semi opaque
finishes like blonde, sunburst, and Dupont colors.
As far as the subtle differences between woods go, it is really
a subjective decision whether one sounds better than another.
Actually none of them sound better, just differant. Exotic woods
are used mainly because they are pretty, as apposed to sound
reasons. Although there may be some sound considerations, most
people buy exotic wooden instruments because of the beautiful
looks more than the sweet sound. If I am going to pay over $1000
for a guitar, it damn well better feature a nice natural wooden
finish. That's why I can't see spending big bucks on an instrument
with a a fancy graphic paintjob. Paint has traditionally been
used to cover over plain woods.
The laminations used on some of the more exotic instruments are
simply an extention of the art. Since quarter-sawn logs are not
wide enough to make a guitar body in one piece, 2-3 piece instruments
have been the standard. Since manufacturers have been making neck
through body instruments, the laminations have become more
complicatied, and more ornate.
that will be 2c, please.

You're talking about *electric* guitars, right? Most serious players
of acoustic instruments (that I know) don't give a dime what the
thing looks like, if it has the right sound. But then you didn't
say anything about *serious* players, did you? You may be right.

942.4 | seriously !!! | ANT::JACQUES | | Wed Oct 26 1988 10:32 | 40 |
| As far as I'm concerned, anyone that enjoys music, and invests
their time and money into it (whether they are into it on a pro-
fessional, semi-pro, or hobby level) can be considered serious
musicians. I have a problem with people suggesting that only
working musicians playing a certain type of music are serious.
When it comes to acoustic instruments, sound is first and fourmost
in my book, but I like an instrument to look good as well, especially
if I am paying a high price for it. It better look as good as it
sounds.
I was referring to electic guitars, since the Base note seems
to be directed towards solid-body electrics. The people that
were involved with inventing the solid body guitar (Les Paul,
Paul Bigsby, Leo Fender, etc.) were all using hard solid wood
bodies to eliminate resonance almost entirely. The idea was to
eliminate problems with feedback associated with amplifying
hollow instruments. This was the whole idea behind Les Pauls
"log" guitar which was constructed from a railroad tie.
Over the years, luthiers have found a happy medium point where a
guitar could be feedback-free, and still have some natural acoustic
properties. An example would be a Gibson ES335 which has a solid
core with hollow wings. The wings are not just for looks. They
give the instrument it's tone, while the solid center prevents
the pickups from "booming".
Naturally, all woods have their own characteristic tone, but whether
wood A is better than wood B is very subjective. I have seen numerous
people that believe rosewood is best for acoustic guitars. I recently
read an interview with Leo Kottke. He believes that mahogony is
best. Who's opinion counts ? Everyones' opinion counts, but the one
opinion that counts the most is the person playing/buying the
instrument.
Again this is just my humble opinion. Of course, I am not really a
"serious" musician.

942.5 | use determines "best" | SPHINX::WEBER | | Wed Oct 26 1988 14:31 | 30 |
| A lot of what is "better" in wood depends on the use. Many bluegrass
players use D-28's because the rosewood bodies are loud, ringing,
and full-bodied, but a studio player will more likely use a mahogany
bodied D-18 for its tighter, more controllable sound.
The top, back, sides, and neck of an acoustic guitar contribute
to the sound in that order. The quality of the top and the method
and quality of bracing or carving probably outweigh all the other
choices put together as to whether a guitar will sound "good" or
not.
However, no one has ever made a great acoustic archtop out of anything
but maple for the body and spruce for the top, though there are
some good electric archtops with birch sides. Once you add built-in
pickups, there is a lot more flexibilty: for example, some of the
best-sounding electric archtops use laminated maple. The laminations
reduce the boominess caused by low-frequency feedback.
As to how much effect the choice of woods has on a solidbody, I
think that pickup variations tends to be an overriding factor, but
all things being equal, a discerning ear can hear the difference
between a mahogany and a maple body, or even a rosewood vs an ebony
vs a maple fingerboard, but...
Things are almost never equal. A good example is that Gibson built
Goldtops mostly with maple tops, but sometimes used LP custom bodies
instead, which were all mahogany in the 50's. At the time, no one
noticed.

Pretty interesting stuff about archtop construction. I'd argue
with you on the fact that no-one "noticed" the differences between
mahogany and maple top LP's though. I'm sure some people did.
Plenty of people are hip to the fact that even Strats made of the
same wood (alder) vary significantly in weight and sound. Some
folks care about this sort of thing, some folks don't.

I used the past tense intentionally. Players in the late '50's were
far less analytical about instruments than now. Remember, there
were no guitar publications, no guitar books, no how-to videos,
no vintage dealers.
There were only a handful of manufacturers: Gibson, Guild, Gretsch,
Epiphone, Rick, Fender and Harmony. Few players knew what type of wood
a Strat or Tele was made of. I knew players who assumed that an LP Custom
had a maple top because it was more expensive than a Standard. There
was no way to experiment: all the hardware was produced by either
the guitar companies, or companies like Kluson, which only dealt
with the manufacturers.
The whole explosion of solidbody makers in the '70's can be laid
to the fact that it became possible to buy high-quality hardware
"over-the-counter", meaning that anyone with a saw and some wood
could build a guitar. Up to that point, there was little
experimentation with different woods, pickups, construction techniques,
etc, outside of what the major makers had done.
There was little interest from most players in "sound" in general,
until the mid-'60's. Looks and feel tended to be the primary
influences for rock players. Consider that Chuck Berry used an ES-350T
and Scotty Moore used an L5-CES, despite the fact that there were
Les Pauls and Teles in existence that were more suited to the music
they were making, but these players were too used to the feel
of their traditional type guitars to switch.
Most players then knew that Strats ,LPs, Chets and Capris
sounded different from each other, but the structural,hardware and pickup
differences were more than enough to explain that without worrying
about the type of wood.
One other point: Fender used Alder for all most guitar bodies, unless
they were Blonde, in which case the prettier-grained Ash was used.
I never heard anyone back then state that the Blonde ones sounded different,
but they obviously did.

I've certainly never suggested that. My definition of a serious
musician is one who takes his/her music seriously for a serious
length of time. My point was that, of the serious acoustic players
I know, most really don't consider appearance in choosing a guitar.
Some tend to prefer the rosewood sound, some prefer mahogany. But
it takes some experience to appreciate the differences, and most
guitars are probably not bought by people with that appreciation.

942.9 | but seriously folks !! | ANT::JACQUES | | Tue Nov 01 1988 08:20 | 18 |
| No offense taken. My point is that some great guitarists are very
analytical about thier instruments and other great guitarists
are not. An example would be David Gilmore of Pink Floyd. Certainly
David Gimore is a serious guitarist, however, he isn't too fussy
about his Stratocasters. He believes he can walk into most any
music store, pull a Strat off the rack, and a couple of effects
and an amp, and he can get "his" sound. Other Guitarists have
analyzed the instrument and their playing style to the nth degree
and can notice the slightest differance in their gear. I could
probably walk into most music stores, choose an acoustic off the
shelf and be content with it. Others have to have an instrument
custom made to their specs or they are not comfortable.
To each his own.

942.10 | woody things | TRUCKS::JANSEN_J | | Fri Dec 02 1988 08:11 | 26 |
| Okay let's get this one straight...
The wood of a solid body is the critical thing on the guitar,I suggest
checking out Melvyn Hiscock's book "Build your own guitar".
The wood affects the sustain capabilities of a guitar which is why
Fender tend to use Ash or Alder bodies (soft bodies) with a rock
maple neck to get the distinctive sound.
Apparently the choice of Ash for the original Broadcaster guitar
was because it looked good on monochrome TV but I don't know if
this is an old wives tale or not.
There is a distinct difference between the earlier and latter Gibson
335s,the earlier ones having a mahogony neck have a far mellower
tone.
Another good example are the Walnut Strats produced in the early
80's by Fender.
The best source of info on this subject is a guitar builder,someone
who's living depends on their knowledge of the subject.
I have a Telcaster made out of basewood,with macau ash veneer and
a Birds eye maple neck and a Strat made entirely out of Bubinga.
I also have some unexotic guitars.

Re: .14
#1 is the classic Martin D-28 combination, although if you substitute
mahogany for the back and sides you get the D-18.
If the Martin sound is what you like, that's the way to go.
One reason a lot of folks have switched away from rosewood for backs
and sides is that it's hard to come by in large enough pieces, thus
the 3-piece back on a Martin D-35.

| Re: .14
While the wood does make a difference, I would think that the size and
construction techniques would make a bigger difference. I have been considering
having a custom Martin built. Here are some of my thoughts:
The top is where much of the sound is produced. The mahogany top of choice 4)
in note .14 would not be anywhere near the best choice. There seem to be
several types of spruce. Martin uses primarily Sitka spruce but a whiter
German(?) spruce is also used. I have hear some people say that they can hear
a difference. I have noticed that the guitars that I have liked have tended
to have close, evenly spaced grain.
Perhaps more important that the wood on the top is the bracing underneath. I
think that you can hear the difference with scalloped bracing. The wood used
for the bridge plate can be a number of things (maple and rosewood seem to come
up often). And then there is the tuning/voicing of the top. I understand that
Martin does not "voice" individual instruments. I understand that they have
an arrangement with some famous guitarist and a master guitar builder whereby
Martin does the assembly and lets the master builder choose the wood and to the
voicing of each top and instrument. I don't know how or if you could get Martin
to have a particular top "voiced" or if this would be worth the trouble.
I have a preference for rosewood for the sides and back. Brazilian rosewood
seems to have the best reputation and is very pretty and expensive. I am a firm
believer in 2 piece backs. I owned a Martin with a 3 piece back and thought
the tone was too mellow.
None of the choices for fingerboards in .14 were ebony which I think is the way
to go.
Mahogany necks seem to be the standard for the highest quality instruments. I
have wondered why Rosewood is never used. It would be prettier - I suspect that
it may not have quite as good structural characteristics. I might be willing
to do some minimal periodic neck adjustment for the aestetics of the prettier
neck. I suspect that the difference in the sound created would be minimal to
nil.
Then there is the body size. I have been playing Martin D size for many years.
This size has the volume and is excellent for blue-grass types. Some people
think that the smaller instruments such as the 000 or OM have a better sound
(clearer with more high frequencies). At the same time, jumbo guitars seem to
be the new rage at Martin.
I have recently sent my D-28 back to Martin to have the neck reset and some
other minor work. I bought it new in '73 and this will be the first work I
have had done on it. I am looking forward to getting it back and seeing what
the level of work is like. I was told by one of the people at the Music
Emporium that Martin likes seeing older instuments in excellent condition
returned for minor work from the orginal owners.

942.19 | Other possible woods | CSC32::MOLLER | Nightmare on Sesame Street | Mon Jul 31 1989 15:46 | 17 |
| Another top wood to consider is redwood. A number of luthiers
are building guitars with redwood tops & have found them to
be as good as any Sitka Spruce top that they have used. I played
one a few years ago (a shop in the Seattle area had one), and
I liked the sound (ie, clear and warm), more like spruce than
mahogany.
Why are so many necks made out of Honduras Mahogany?? Because its
a very stable and strong wood, and it's also easy to work and
gives a warmer tone to the guitar. Maple necks tend to make the
guitar too bright. A Rosewood neck is possible (and occasionally
done on solid body guitars), but I'd think it too heavy and
unstable (ebony, when dry is quite stable, rosewood is not bad,
but Mahogany and Maple are more stable) as well as too expensive
to do except on special order cases.

I believe that's what is also referred to as western red cedar, used as the
top in most Ramirez classical guitars. I've found - in my non-statistical
sample - that cedar tops give a slightly darker/warmer tone than spruce.
Luthiers have told me that spruce takes longer to 'settle in' than cedar.
If a steel-string guitar is well made and voiced, then the choice of rosewood
vs mahogany is just a matter of taste. Rosewood is a more expensive wood
mainly because of its appearance. The case of classical guitars is harder to
judge since there are so few high-quality mahogany instruments made.
Pierre Bensusan plays a mahogany guitar and loves it.

I spoke with a large Martin dealer yesterday about the new model from Martin,
the HD-28MP Morado. This guitar is identical to the HD-28 except that it is
made out of Bolivian rosewood (and $141 cheaper). This person said that India
had put an embargo on India rosewood tree exports, that Indian rosewood would
soon go the way of Brazilian rosewood and that Martin was buying all of the
Indian (and Brazilian) rosewood available. She said to expect Indian rosewood
to become an extra charge option in the future (3 years??) and that the price
of Brazilian rosewood to climb out of sight ($2500 extra over "standard"
rosewood). This dealer had heard that the Bolivian rosewood was not quite
as nice sounding as the Indian or Brazilian wood.
Has anyone heard anything about limits on the availability of Indian rosewood?
Brazilian rosewood does seem to be getting quite scarce.

942.22 | Improves with Age: Wood and Sound | PSYLO::WILSON | | Mon Nov 19 1990 14:32 | 10 |
| Here's one for the members of this conference to discuss: what is it
about wood in an acoustic guitar that, after time, creates a "mellower"
sound? The sticker on Washburn acosutics says "IMPROVES WITH AGE" or
somesuch.
And what of electrics? Can they, too, be expected to improve with age
because of wood changes?
I'm really baffled by this!
|
942.23 | | E::EVANS | | Tue Nov 20 1990 09:55 | 8 |

Most wood in acoustic guitars is aged before it goes into the guitar. While I
suspect there may be some changes in the wood, the biggest changes occur in the
setting of the glue and lacquer finish. I expect the same would be true for
electrics, only that the change would be less noticeable.
