This is a combined instrument of the Turkish instrument Saz and the Japanese Shamisen. Thanks to the double body, the low frequencies are even more powerful. The soundboard and backboard are made of Kiso Hinoki cypress. Unlike the Saz, which is equipped with wound gut frets, this instrument is fretless like the Shamisen, allowing for more subtle pitches. The strings use metal strings for the Saz. A set of replacement strings and a Saz pick are included. It is recommended to tune it from low to high as GDA. You can search for "Shazsen Double Body Test Play" on the video site Vimeo to see it.
