The woods


Imbuia is easily found in the Southern region, frequently in Paraná, Santa Catarina and Rio Grande do Sul states.

With medium density and texture, color varying from pale yellowish to brownish brown, usually with dark veins forming very characteristic and exotic irregular designs, easy to be crafted, which allows a good finish.


With wide distribution in the Amazon region, frequently found in Acre, Amapá, Amazonas, Pará and Rondônia states.

Low density wood, medium to thick texture, beige-pink color, with veins forming smooth regular designs, easy to be crafted, which allows a good finish.


Pau-Ferro is a wood often found in the states of Goiás, Minas Gerais, Espírito Santo, São Paulo and Paraná. It is also found in Bolivia.

It’s a density moderately heavy and very durable wood, with a color varying from light-yellow-brown to brown, usually with dark veins forming very characteristic and exotic irregular designs, reasonably difficult to be crafted, but allowing for a good quality finish.

Sitka Spruce

One of a few non-brazilian wood used in the production of our national instruments. You can find Sitka Spruce in North America.

It is a cream-colored, light pink or brown wood, quite abundant and which results in instruments with good sound projection and a very “lively” sound, with a lot of attack, with a clear tone and it is possible to keep the notes highlighted even with the strong dynamics.
