Uses

The genus is well known for its luxury timbers. The best-known timber is bubinga (Guibourtia demeusei, aka kevazingo). Another is ovangkol. Species of Guibourtia also produce Congo copal.

The wood is often used by luthiers for harps and other instruments, such as bass guitars, because of its mellow and well-rounded sound. Warwick Bass and Ibanez are known to use Bubinga and Ovangkol. It has been used in drum shells as well. Drum companies such as Tama offer various high-end drum kits with plies of Bubinga in the shells.^[4] Crafter also use bubinga on some of their instruments.^[5] Bubinga is also used in both acoustic and electric guitars for its figure and hardness.

Bubinga is also used in high-end furniture, especially by contemporary Arts and Craft artists. Bubinga comes in various grain patterns, with rare patterns bringing top dollar.
