Has
a very powerful sound; complexity, and richness in tone. Strong and tight
basses, with softer midrange, crystal clean and smooth on high frequencies.
Produces a very projective sound; even slightly mellow. Great for Classical and
acoustic Jazz guitars.
Used
in fingerboards, is a very good partner to harsh woods, finding the balance to
excessive crispy guitar sets.
The
grain is interlocked with a medium texture which helps very much on the
resonance and sustain overall.
The
wood is rather difficult to saw and work, gluing can be difficult because of
the presence of exudates in the wood but finishes very well.
The wood is moderately
heavy, is very stiff and very resistant with an average
dried weight nearly of - 940 kg/m3.
It
is native from the savanna zone, from Senegal and Gambia to Chad and the
Central African Republic.

buttressed; bark surface greyish brown to blackish, fissured and scaly, inner
bark yellowish brown, with reddish streaks, exuding a reddish translucent gum
on slashing; crown rounded, open; twigs densely short-hairy when young.
