This instrument was firstly created by U Dee Yaw Hel and played in the 19th National Races Traditional performing Arts Competition. First, halve a piece of cassia wood with a length of two and half feet in order to carve it into the guitar body. The reason of having two frets is to produce traditional tunes of two Chain-ngo and Gwar-chichi-bu guitars. Each fret has four strings and there are six sound holes on the guitar body. The upper fret makes Gwar-chi-chi-bu sound and the lower one produces Chain-ngo sound. This two fretted guitar is created to play these two traditional tunes in the same time, instead of playing two guitars.\n-2 feet 7 inches in Length\n-1 feet 2 inches in Length of guitar body\n-10 inches in Width of guitar body\n-2.5 inches in Thickness of fret\n-1 feet 5 inches in Length of fret\n-3 inches in Distance between two frets
