White Oak (Primary background) and Sitka Spruce (Foreground strip)
Quercus alba (Oak) / Picea sitchensis (Spruce) • Hardwood (Oak) and Softwood (Spruce)
Grain Pattern
Oak: Flat-sawn with prominent medullary rays and large open pores. Spruce: Extremely tight, straight vertical grain (quarter-sawn) representing high-quality tonewood.
Color Description
Oak: Light to medium brown with a slight olive cast. Spruce: Nearly white to creamy yellow with a high silky luster and consistent color.
Hardness Rating
Oak: 1,360 lbf (Hard). Spruce: 510 lbf (Soft).
Durability Rating
Oak: Very Durable, rot-resistant. Spruce: Non-durable to Slightly Durable, prone to decay if exposed to moisture.
Common Uses
Oak: Flooring, cabinetry, furniture, boat building. Spruce: Acoustic guitar soundboards, piano soundboards, aircraft components.
Geographic Origin
Oak: Eastern North America. Spruce: Pacific Northwest (Alaska to Northern California).
Market Value & Sustainability
Estimated Market Value
Oak: $6-$10 per board foot. Spruce (Master Grade): $50-$100+ per soundboard set/board foot equivalent.
Wood Age Estimate
Recently milled/modern stock. The spruce shows no UV darkening and the oak has a fresh factory finish or raw sanded state.
Sustainability Status
Both are generally LC (Least Concern) on IUCN, though high-grade old-growth Sitka Spruce is increasingly rare and monitored.
Workability
Oak: Hard to work by hand, prone to splintering, glues well. Spruce: Excellent workability with sharp tools, very easy to plane; extremely sensitive to bruising.
Notable Features
Oak has high tannin content and a distinct vinegar-like scent. Spruce has an exceptional strength-to-weight ratio and renowned acoustic resonance.
Finish Recommendations
Oak: Oil-based finishes to pop grain or polyurethane. Spruce: Traditional nitrocellulose lacquer or light shellac to preserve acoustic properties.
Identification Confidence
High. The wide, open pores and rays identify the Oak; the ultra-fine, perfectly straight grain lines and light color are characteristic of premium Spruce tonewood.
