IT'S banjo with side and back of Rosewood. Ebony scale and golden tuners. 

The banjo's hoops are in aluminum bathed in gold or onyx, and handmade. The leather is goat.

It is a professional level instrument with sound quality and tuning accurate. And it can be purchased acoustic or electroacoustic with Fishiman (USA) model SBT pickup.

The hardwoods are of  great selection, with advanced level and AA rating. And an interesting detail is the fasten strings, being practical in the placement of the ropes and also serving as a belt pin.

This instrument has been in great demand by most of the groups in samba and pagode, and still sent to other countries.
