Hailed for his rich tone and charismatic playing, Korean-American cellist, MARK BAEKBEOM YEE has a career as a soloist, chamber musician, and orchestral performer. As winner of the Cleveland Institute of Music concerto competition..

"I was so pleased with the results of switching to the Tone Acoustics endpin, I decided to see if Tom’s rock stop could enhance the sound of my cello even more. The answer was YES! The rock stop added a more round and focused sound to the instrument. Now, when I play, I have the feeling that the cello has more power to give -- I can feel more layers are added to the sound. The rock stop produces more overtones to my ear, and works particularly well in a room-like setting. For those who have auditions for schools or professional auditions, this rock stop can give one that extra edge to the sound of your cello."
