Fox Bocal Information


In 2010, Fox introduced a new line of their already very popular double star bocals, the R2. These bocals are even in tone color and responsive across the range. There are some variables to look at when considering a Fox bocal.

All of the Fox double-star R2 bocals start with the letter C, followed by two letters that indicate first the thickness, then the bore type.

T – “Thin-wall” These are similar to the Heckel CD bocal line, roughly .5mm thick throughout the wall of the bocal. The thinner wall means greater flexibility of tone character and typically an easier responding lower register.
V – Standard thickness. Similar to the Heckel CC thickness, with an average of .6mm through the wall of the bocal. Best for stability and more projection.

C – The standard bore. This is most commonly a match for thick-walled instruments like the 601 or 660. This bore offers the best core to the sound with a consistent response.
X – Slightly larger bore. This bore has a tendency towards ease of response in the extreme registers, and is a favored match for the thin-walled Fox bassoons like the 240 and 201.

Material is not indicated by letter markings on the bocal. Most commonly Fox bocals come in silver-plated nickel-silver alloy, although an unplated brass alloy is also available. Gold-plating is available as an option for a cost.

Fox bocals are sold in lengths that are off by a factor of 1 from Heckel. A Fox #2 length is equal to a Heckel #1, and a Fox #3 is equal to a Heckel #2. Fox will produce lengths 0-4.

Fox produces a traditional S bend as well as British bend bocals. We have begun stocking more of the British bend *CVC* bocals in both standard metal and plating as well as brass.
