Sub Tu-Yo
The Sub Tu-Yo is an acoustic instrument that is part of the Tu-Yo family.
Made of long tube lengths of different materials (plastic, cardboard, aluminum, etc.), it works in the same way as the Tu-Yo (latex membrane covering one end, inside of which we blow air). Its sound palette is made up of very deep rumbling and roaring rather in the low and over low register, hence its name.
