The Guitarron is tuned 1 octave lower than the prime guitar. The strings are very thick, and the body is very big. The sound is so unique completely unlike the others. It is the most important guitar in a guitar orchestra because the rich and warm sound wraps the whole sound of the guitar orchestra in its deep bosom. Its origin is in South America, and Dr. Niibori attached an end-pin to it and changed the style of play. It has the same range as the contrabass guitar. The dynamic style of playing attracts people's attention everywhere.
