Sitka spruce is a traditional choice for steel-string guitar soundboards.
Bookmatched sets of two quartersawn halves. When joined they're large enough for a Dreadnought guitar.
- Each half is approximately 8-1/2" x 21" (216mm x 533mm)
- Thickness-sanded to 0.125" - 0.130" (3.18mm - 3.30mm)
- Unsanded tops are approx. 5/32" (4mm) thick, ready for thickness-sanding to your own specs.
Use our grading system to choose your soundboard...
Color: Higher soundboard grades have more consistent color (color affects the instrument's appearance only, not its tone).
Grain straightness: Higher soundboard grades have straighter, more uniform grain due to slower wood growth, with more grain lines per inch. Variations in grain straightness generally don't affect the wood's structural integrity. Closely spaced grain has been traditionally favored, but luthiers have found that wider grain can produce very good tone.
Quartersawn grain: The higher the grade, the more closely quartersawn the wood. Higher grade soundboards are usually stiffer, stronger and more resilient, and less likely to deform under string tension.
Grain run-out: Our soundboards are sawn from split billets to reduce the amount of grain "run-out," caused by a twist in the tree. By splitting the log, the twist is followed when sawing. Higher grade soundboards have less run-out, for more strength. However, properly braced lower grades can be excellent soundboards, especially for classical guitars. Engelmann spruce trees grow at higher altitudes, and usually have some run-out due to their smaller diameters.
Origin and drying: Our soundboards (except Red Spruce) are from western North America, and have been kiln-dried and stored for up to a year.
