Shedua (Guibourtia ehie), also called Ovangkol, is a West African hardwood and a cousin of Bubinga, though it looks quite different. It's a popular African tonewood.The heartwood ranges from light to medium yellow to light orange or reddish-brown, usually with darker brown or black stripes, and the sapwood is pale yellow. Tiger stripe, fiddleback and mottled figure turn up on occasion, and boards can vary so much they look like different species.The grain can be straight, wavy or interlocked, with a medium texture and nice luster. It's tough and durable and generally works well, though its silica can gum up blades, and interlocked boards can tear out. It turns, glues and finishes well.Guitar makers use it as a rosewood alternative for backs and sides, with a similar warm tone, and some denser pieces are used for fretboards. It's also used for electric guitar bodies, furniture, cabinetry, flooring, trim, turnings and veneer.
