Scientific Name: Guibourtia demeusei, Guibourtia tessmannii, Guibourtia pellegriniana
Origin: Native to Central and West Africa, primarily found in Cameroon, Gabon, and the Congo Basin.
CITES Status: Listed under CITES Appendix II (regulated trade due to concerns over overharvesting).
Use in Guitar Making
Bubinga is used for acoustic guitar backs and sides, electric guitar bodies, and occasionally for necks and fingerboards. It is sometimes used as a substitute for rosewood due to its similar tonal characteristics and striking appearance.
Tonal Properties
Bubinga offers a rich, full-bodied sound with a pronounced low end and strong sustain. It is often compared to rosewood but with a slightly brighter top end and more pronounced overtones. Its density contributes to a focused and articulate tone, making it ideal for percussive and dynamic playing styles.
Hardness and Workability
Janka Hardness Rating: Approximately 2,410 lbf (10,700 N)
Bubinga is an extremely hard and dense wood, making it highly durable but challenging to work with. It requires sharp tools and careful handling to prevent tear-out. Due to its high density, it can be difficult to bend for acoustic guitar construction, though it finishes well with proper preparation.
Grain Structure and Porosity
Bubinga has a fine to medium texture with a straight to slightly interlocked grain. Figured varieties, such as pommele and waterfall bubinga, exhibit striking patterns that enhance its visual appeal. It has a moderately open grain that may require filling before finishing.
Sustainability and Ethical Considerations
Bubinga’s inclusion under CITES Appendix II means that international trade is restricted, and proper documentation is required for export. Overharvesting has led to concerns about its long-term sustainability, encouraging luthiers to seek alternative woods or responsibly sourced bubinga.
Bubinga remains a desirable choice for high-end guitar making, offering tonal richness, durability, and a stunning visual appeal. Its continued use depends on responsible sourcing and compliance with international trade regulations.
