Wood on C. F. Martin Guitars
It appears that the first guitars made by C.F. Martin after
coming to New York in the 1830's may have been made with tops
of Alpine Spruce from Europe.

Most vintage Martin guitars are built with tops made with
Spruce which is often referred to as "Adirondack" as it was
generally sourced from the Adirondack region of the Eastern
US, mostly from suppliers in Vermont, but more properly named
"red spruce".
"Red spruce" is actually quite white, but the shellac used for
finish until the late 1920's can give them a more or less
orange appearance, depending on the color of the shellac,
which can range from light to deep amber.

Without the orange tone often imparted by shellac, red spruce
is generally pale and even in color, in addition to having a
uniform, even, straight grain.

The top wood seen on the highest grade Martins can be
extremely pale and even, leading us to think that Martin might
have used the light toned European spruce for their better
quality guitars.
This wood can be confused with German spruce which has a
similar pace appearance, however "German Spruce" is in fact a
variety of spruce grown in America.
It is generally believed that German spruce was used for the
pearl inlaid Martins produced after their revival in the
1960's.
Martin Style 42



While Sitka Spruce is thought to have been used for Martin
tops only after WWII, Martin broke briefly with
tradition in experimenting with Sitka Spruce, known at the
time
as "Airplane Spruce", for the tops of some guitars in 1919,
when Western Spruce was being harvested for the construction
of WWI airplanes.
Sitka can often be distinguished by darker, reddish grain
lines, a less even appearance, and prominent resin canals
which cross the grain of the spruce.

Martin Style 42 and 45 guitars are
generally known for the appearance of their pearl, however the
selection of a higher grade of spruce and all other materials
is responsible for much
of the cost and attention paid in building the higher priced
Martins.
The finest materials of all were reserved for the 45 DeLuxe,
which were only available for a number of months.

Red Spruce can sometimes be distinguished from Sitka by the
appearance of sapwood, which has a lighter appearance.
Sapwood could be placed at the sides of the tops,
but was generally placed at the middle, forming a light
colored band in the center of the top. Sapwood appears
on Engelmann and German Spruce as well, but never on
Sitka.
Sapwood is seen most often on Martins from the 1940's, when a
greater number of larger guitars were built. Red spruce
trees are extremely small compared to the giant Sitka,
so it became difficult to find wide enough logs to accommodate
000 and Dreadnaught guitars without using the sapwood,
especially as the supplies of appropriate red spruce
dwindled.

In 1946, as supplies of their preferred sources of spruce
dried up, and Martin had used the last smaller pieces to
create four piece tops, Martin began switching to Sitka spruce
from the Northwest.
The Sitka used in this first year of 1946 has a distinctive
dark brownish tone, and tends to have the distinctive light
swirls in the wood known as "bear claw".
This figure is considered to be desirable as it can make the
board stiffer as well as for it's appearance.
1946 Martin 000-18

1952 Martin 000-18

In 1953 Martin used a batch of Engelmann Spruce which was
acquired as government surplus wood. It is possible that
Martin also acquired a small supply of red spruce which was
also used in 1953.
Martin also acquired a supply of red spruce which appears on
some Martin guitars built in 1957.

In 1922 Martin introduced the 2-17 with a mahogany top as well
as back and sides. The Style 17 line was soon
expanded to include single 0 and 00 guitars.
1936 Martin 0-17

An all mahogany Style 15 was added to the Martin line in 1940.
A variety of woods were used for the backs and sides of early
Martin guitars, including Brazilian rosewood, birds's eye and
flame maple, and Goncoa Alves.
Most of the higher quality early Martin guitar backs were
constructed with a hardwood veneer over either mahogany or
spruce.

This Martin & Coupa guitar is one
of two generally thought to be unusual early examples made
with koa wood.

It is actually made from Goncoa Alves, sometimes referred to
as "tigerwood".


The back of this guitar is made in two pieces, joined without
either interior or exterior center strip.

By the 1840's, most all Martins were made with solid or
veneered rosewood backs and sides.
By 1900, rather than buying 1/10" or 1/12" rosewood veneers
for backs and sides, Martin was buying whole logs of Brazilian
rosewood which they had sawn into veneers. Martin
purchased Brazilian rosewood in logs as large as 5340 lbs.

Mahogany was extremely rare on 19th Century Martin Guitars,
appearing primarily on a small number of Style 3-16.
This early example has beautiful striped mahogany.


Once Frank Henry Martin began tinkering with the product
lineup after the turn of the Century, the Style 17 reappeared
as a "budget model" with mahogany backs and sides in
1906.
Martin's use of wood changed dramatically in 1916 when the
Southern California Music Company provided Koa wood from
Hawaii for a new line of Hawaiian guitars, and this blossomed
into a huge number of best selling Hawaiian Koa wood Martins.
While the Style 18 Martins are generally recognized today by
their mahogany backs and sides, the mahogany backs and sides
did not appear on a Style 18 until Frank Henry expanded the
use of mahogany to the Style 18 in 1917, helping Martin to
succeed at achieving their goal of increasing sales, and the
less expensive mahogany Martins became the company's larges
sellers by far.

and higher models have always had ebony fingerboards and
bridges, while lower models began with ebony bridges.
The Style 18 Dreadnaughts kept their ebony
fingerboards and bridges until switching to rosewood in
1947.
On the smaller models, most Style 18 Martins switched
to rosewood fingerboards and bridges in 1935, but for that
year only. After 1935, fingerboards and bridges on
Styles 21 and below made a slow transition from ebony to
rosewood lasting into the 1940's.

Martin Hawaiians
In July of 1916, with Hawaiian music all the rage, the C. F.
Martin Co. shipped six samples each, of Hawaiian koa wood
guitars with appointments generally similar to
Martin's styles 0-18, 0-21, and 00-28, to the Southern
California Music Company of Los Angeles, a chain of
SouthernCalifornia music stores, and one of Martin's largest
accounts. SoCal provided Martin with the koa wood from Hawaii,
and asked that the trim on these guitars, designed for playing in the Hawaiian style, be as close as possible to those of SoCal's
popular ukuleles. These early
samples had koa wood back and sides and tinted spruce tops,
but after seeing the samples, SoCal decided to offer all koa
guitars, and to market the three models as the 1350, 1400, and
1500.

The koa on the SoCal Martins varied tremendously, some highly
flamed and some rather plain.


The fancier koa was sometimes but not always used on the
higher grade models, however, since it was not always
available. The guitar on the right in the
photo of two examples above is the higher grade Model 1500.
The Change from Brazilian Rosewood to East
Indian Rosewood.
In 1965 when the supply of Brazilian rosewood large enough for
Dreadnaught size backs was dwindling, Martin began to produce
the D-35 with a three piece back which used smaller pieces of
rosewood which had been cut for sides.

In 1967, Brazil placed an embargo on Brazilian Rosewood Logs,
so only Brazilian Rosewood products made in Brazil could be
exported. Martin had been buying whole logs and had
built their own facility to cut the wood into veneers for use
on their guitar. From this point on, Martin had to rely
on whatever supply of Brazilian Rosewood they had left.
On December 1, 1969, Martin switched to East Indian
Rosewood with a D-21 in Shop Order #105, with serial
#254498. For the early D-35, Martin used what Brazilian
Rosewood they had left for the center portion of the three
piece back, with East Indian Rosewood for the outer two
portions.
The Serial and Shop Order Numbers were not always stamped in
the same order, so the D-28 with the later Serial number
254748-72 and Shop Order #115 were built with Brazilian
Rosewood despite the higher numbers since they were stamped
earlier on November 28.


While most Martin fans love
Brazilian rosewood and believe it to be superior, Frank Henry
Martin was also a fan of East Indian Rosewood. When
Martin hardwood supplier Ichabod T Wiliams sent a sample of ER
in 1924, Martin was "immensely pleased". "it is not only
unusually fine wood, but it is also remarkably well sawn, and
we wish to compliment you on the shipment.
...whenever you get such a flitch you my manufacture it for us
without further instructions." Martin bought EIR from
Williams in 1924, 1926, and again in 1932.
