The sound board of the
instrument is split laterally and longitudinal with the use of strips of darker
wood, probably searching for a particular sound instead of an ornament to use.
The appearance is analogous to a bandolin that is found in Ecuador, the
Peruvian Marimacho Bandurria and specifically the ‘Laud’.
