A thin wall bocal designed to increase the response of a thick wall instrument.
A new level of quality with the latest advances in materials and design. Introduced in 2002, the *CTC* bocals are now supplied with all Fox 601 and 660 bassoons. These bocals have thinner walls and have greatly increased their flexibility as well as being even more free-blowing. The *CTC* is particularly desirable for thick wall bassoons, and Heckel bassoons made since 1960. Made of a silver-plated nickel silver tube.
