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

In most of the years before World War II, Martin used wood for their tops
often called "Adirondack Spruce" as it was generally sourced from the
Adirondack region of the Eastern US, mostly from suppliers in Vermont, but
more properly named "red spruce".
The finish can affect the appearance of early Martin guitars, as Martin
often used shellacs which added an orange tone.
1840's Alternate X Brace Spanish Style Martin
Without the orange tone sometimes imparted by shellac, the top wood on
early Martins is generally pale and even in tone, in addition to having a
uniform even, straight grain.

The top wood seen on the highest grade Martins is extremely pale and even,
leading one to think that Martin might have used European spruce for their
best pearl inlaid guitars.
The question is confused by the fact that German spruce has a similar pace
appearance, while "German Spruce" is in fact a variety of spruce grown in
America, and it's generally understood that German spruce was used for
pearl inlaid Martins after their revival in the 1960's.
Martin Style 42
In 1919 Martin briefly broke with tradition and used Sitka Spruce, known
at the time as "Airplane Spruce", for the tops of their guitars.
Sitka can often be distinguished by darker, reddish grain lines and
prominent resin canals which cross the grain of the spruce.

Martin used the finest material on their pearl inlaid guitars, and
used the highest grade woods available for the DeLuxe.

Red Spruce can often be distinguished from Sitka Spruce on Martin guitars
by the appearance of sapwood, which could be placed at either side, but
was generally placed by Martin at the middle of the top, forming a light
colored band. 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 more larger
guitars were built. These spruce trees are quite small, as opposed
to the relatively giant Sitka trees, so it became difficult to find enough
wide enough logs to accommodate 000 and Dreadnaught guitars without using
the sapwood, especially as the supplies of appropriate red spruce

In 1946, as supplies of their preferred sources of spruce dried up, and
Martin had used the last smaller pieces to creat four piece tops, Martin
began using 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.

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

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.
Most early high quality Martin guitars were made with a hardwood veneer
over either mahogany or spruce.
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
Martin Stauffer Style guitar with maple back and sides.
This Martin & Coupa guitar is one of two thought to be unusual
early examples made with koa wood.
It is actually made from Goncoa Alves, sometimes referred to as
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 rosewood backs and sides.
Many early Martin guitars had backs of rosewood veneer over spruce.

Mahogany backs and sides are extremely rare on 19th Century Martin
Guitars, seen mostly on the early Style 16. This example has
beautiful striped mahogany.
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. The guitar on the right in the photo of
two examples above is the higher grade Model 1500.
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
