All
the woods used
are carefully selected and dried.
Palo
Blanco ( Calycophyllum
multiflorum ) is a very stable semihard wood
whose physical and acoustic properties are equivalent
to those of boxwood.
Guayacán
( Caesalpinia
paraguariensis ) is a beautifully
grained hardwood with tone, hardness and weight
similar to ebony wood.
Both woods allow the
construction of high quality instruments without
the environmental impact of using endangered species.
By the same token, the thumb bushings are made of bone, and the ornamental rings are made of synthetic ivory.
