The Saw bang is a bowed musical instrument. It differs from a related Saw by using only bamboo for its sound box and skull fiddle (กะโหลกซอ). The bamboo is called " Mị̂ ku (ไม้กุ) ". It is sun-dried and then the bark is taken off. Holes are made and strings are stretched with the knob which are made from two pieces of wood wedge.
