This set contains the Cascha Ocean Rock Blues Harmonica in 7 keys (C - D - E - F - G - A - Bb) packed in a practical bag for storage and safe transport of the harmonicas. The Ocean Rock harmonica by CASCHA is ideal for professional players and those who want to become one. With its modern design it is an absolute eyecatcher. The round holes allow an increased air flow, which leads to a loud, rocky sound. The Cascha Ocean not only stands out from the crowd visually, but also meets every challenge in terms of sound.
