The JooJazz – developed by and with Joo Kraus combines a simple and elegant design with symmetrical basic shapes. Pure copper is used in the bell. Musically, the instrument leans and orients towards jazz and U-music, from funky to mellow. Good intonation, not too little resistance, stable even if one pushes in the dynamics.
