Color
Heartwood ranges from pinkish-brown and reddish-brown to darker brown tones. Natural color variation and subtle striping may occur within a board.

Western Red Cedar
Thuja plicata
Lightweight, responsive, and known for its warm tonal character. Western Red Cedar is a respected tonewood widely used for classical and acoustic guitar soundboards.
01
What Is Western Red Cedar?
Origin & Botanical Information
Western Red Cedar (Thuja plicata) is a conifer native to western North America. It belongs to the cypress family (Cupressaceae), rather than the true cedar genus (Cedrus).
The wood is valued for its low weight, ease of working, and distinctive natural aroma. In addition to architectural and woodworking applications, it is widely used by luthiers as a soundboard material.
Alongside various species of spruce, Western Red Cedar is one of the established choices for acoustic and classical guitar tops.

Wood Characteristics
Color, Grain & Workability
Grain
Typically straight-grained, with relatively even texture. Quarter-sawn orientation and growth-ring characteristics are important considerations when selecting soundboards.
Low Density
Western Red Cedar is relatively lightweight. Its density and stiffness are important factors in soundboard design and vibration performance.
Workability
Its soft texture makes it easy to cut and shape with hand tools. However, the surface can dent or bruise easily and requires careful handling.
Western Red Cedar has a distinctive aroma,
but its dust may cause skin or respiratory
irritation and allergic reactions.
Use suitable dust extraction,
ventilation, and protective equipment.
03
Acoustic Properties
Soundboard Performance
Western Red Cedar is often selected for its low density and responsive behavior as a guitar soundboard material. When appropriately designed, a cedar soundboard can respond sensitively to light playing input.
Cedar-topped guitars are often described as having a warm, rounded tonal character. Their sensitivity to subtle playing dynamics makes them popular among classical guitarists and fingerstyle players.
The final sound of an instrument, however, depends on many factors, including the individual wood's stiffness and density, top thickness, bracing design, body construction, and craftsmanship. No single species guarantees a particular tonal result.
04
Western Red Cedar vs. Spruce
Choosing a Guitar Top
Both Western Red Cedar and spruce are widely used as guitar soundboard woods. Each offers characteristics that can influence a luthier's design choices.
Western Red Cedar
Generally lower in density and softer in texture. Frequently chosen for warm tonal character and responsive behavior under light playing input.
Spruce
Many spruce species offer high stiffness relative to weight. Often selected for articulate tonal response and the ability to support a broad dynamic range.
These are general tendencies,
not fixed acoustic rules.
Individual wood properties and
instrument design can produce
substantial differences.
05
Soundboard Quality & Grading
Material Selection
Quality assessment for Western Red Cedar soundboards involves more than appearance. Luthiers evaluate grain orientation, growth-ring patterns, defects, dimensions, and mechanical properties.
Grain Orientation
Straight grain and quarter-sawn orientation are commonly preferred for soundboard construction.
Growth Rings & Color
Ring spacing, uniformity, and color contribute to visual grading. Tighter rings do not automatically mean better sound.
Defects & Dimensions
Knots, cracks, grain deviations, and usable dimensions are important selection factors.
Stiffness & Condition
Density, stiffness, moisture condition, and dimensional stability should be considered for the intended design.
Grade names such as AA, AAA,
and Master are not necessarily
standardized across suppliers.
Always review the actual material,
photographs, dimensions,
and product specifications.
06
Recommended Applications
Musical Instrument Making
Acoustic Guitars
Soundboards for a wide range of acoustic guitar designs, including fingerstyle instruments.
Classical Guitars
A well-established choice for nylon-string guitar tops, especially in designs emphasizing sensitivity and tonal warmth.
Ukuleles
Lightweight tops for ukuleles and other small stringed instruments.
Other String Instruments
Suitable for selected soundboard applications when material properties and structural requirements are carefully evaluated.
07
Working, Drying & Storage
Workshop Considerations
Western Red Cedar is generally easy to work but requires careful handling because of its soft surface. Excessive pressure during machining or sanding can cause dents or uneven surfaces.
Before instrument construction, check the moisture condition of the material and allow it to acclimate to the workshop environment.
Store soundboard sets away from direct sunlight and rapid changes in temperature or humidity. Proper storage helps minimize the risk of distortion and cracking.
08
Selecting the Right Tonewood
For Luthiers & Instrument Makers
Western Red Cedar combines low weight, workability, and distinctive acoustic characteristics, making it a versatile material for soundboard construction.
At Maikai Wood Hawaii, we aim to help luthiers and instrument makers select suitable tonewoods by providing detailed product information, dimensions, and photographs.
