Backun Q Series Bass Clarinets set the standard for what bass clarinet playing should be. Designed with an intense focus on exceptional intonation throughout the registers and a beautifully engineered mechanism, this series of professional bass clarinets has no equal. From the triple register mechanism to over- and under-cut tone holes and a thoughtful custom Marcus Bonna Case, the Q Series Bass Clarinet is a new low, even for Backun.
