Fox type B crook

The Fox B Crook (Bocal) has now replaced the CVC and CTC crooks. The Fox B crook helps favour the lower partials of the bassoon sound to produce greater depth, more power, and a lyrical, dark tone. Fox B crooks are available in lengths 1, 2 and 3, with #1 being the shortest length. The B crooks are manufactured from nickel silver with silver plating.

Fox type T crook

The Fox T Crook (Bocal) has now replaced the CVX and CTX crooks. The T crook helps favour the upper partials of the bassoon sound to produce greater flexibility and easy, expressive performance, especially in the high register. The T crooks are available in lengths 1, 2 and 3, with #1 being the shortest length. The T crooks are manufactured from nickel silver with silver plating.

Fox type C crook

Entry level Fox C Crooks (Bocals)  are manufactured from nickel silver with silver plating. C bocals are available in lengths 1, 2 or 3, with 1 being the shortest. If you do not know the length you need, the #2 is probably your best place to start. Fox C crooks are popular as a replacement crook for school use with most bassoons.
