Tonewood Nomenclature, Grading and Sizes
Nomenclature
This is a BRIEF description of "grade on aesthetics" only. Other criteria are also considered. Any wood that meets the criteria for instrument grade is of the highest quality in the overall spectrum of lumber grading. That high quality is divided into the following grade classifications.Texture is the character of the growth, the ring count. Can be Fine, Coarse, graduating from fine to coarse or somewhat uneven across the board.
Medularies is the cross grain silk that is apparent when a board is cut nearly perfect VG
Stiffness refers to cross grain stiffness
|
Master Grade has very fine even texture, moderate to strong medularies, very even color. One of those "one in a-thousand" tops |
|
Sitka Spruce |
Yellow Cedar |
Western Red Cedar |
AAA Grade also has very even texture and color, but there is just something that makes it not one of those "one in a-thousand" tops. |
Sitka Spruce |
Yellow Cedar |
Western Red Cedar |
AA grade is a NICE Grade that can have even texture but some subtle color or even color with uneven texture. It is the grade used for most moderate priced [$800-$1000] instruments of manufacturers. |
Sitka Spruce

Yellow Cedar |
Western Red Cedar |
A grade still makes a nice instrument with character. Manufacturers use this grade on their models that average $300-$700. It just has an appearance that won,t allow it into the next grade. |
#1 grade is used in the smaller instrument to generalize a- AA/AAA- grades
Double Bass fronts have somewhat different grade criteria in that the texture is considerably coarser over-all, sometimes to ¼" growth ring.
Figured Spruce is divided into 3 categories:
#2 grade is used in the smaller instrument to generalize a- A-/AA- grades
As the name implies, it looks as if a bear had dragged it,s claws across the grain, pulling it in that spot. The way it,s cut will alter that effect somewhat. The curl is not the the real strong curl found in Maples, but is more subtle. It is still a beautiful effect of depth.

Ordering notes
From the ONLINE
STORE you will see most of what we cut and or stock.
If something is not listed, we can most likely cut it for you.
If you are rebuilding an instrument that is
peculilar in size, like a bouzouki, or if you are building an over-size mandolin (and the regular top is too small and the archtop guitar is too big) contact me. I may have stock that is just right or just slightly oversize, such as a small body archtop.
