Here we have a Double Top guitar from one of Brazil’s foremost luthiers Samuel Carvalho. The top is two layers of Cedar with a Nomex core. This construction allows for lighter bracing and produces a loud, clear guitar. The back and sides are Indian Rosewood and the sides are doubled for added stiffness and greater projection. It’s no wonder a number of Brazil’s top players choose Carvalho guitars including Paulo Porto Alegre and Paulo Martelli.
