Puchner Bocal Information


Puchner is historically one of the most well-respected bassoon manufacturing firms in the world, with a history dating back to the early 19th century. Puchner bocals have undergone many revisions through the years, with modern bocals finding their way to many major symphony and concert halls across the country. While other manufacturers have dozens of variables, Puchner stays with only some options that suit the needs of most players.

Puchner-bassoon-bocalThe first letter will indicate the bore, which will be followed by a letter indicating the metal and thickness. All bocals are silver plated. Available in standard lengths 0-3 (equal to Heckel lengths)

There are three bores available:
C – the C bore is the standard bore that offers excellent response in all registers and makes for a good orchestral or chamber music bocal.
B – the B bore has a more focused sound with more “core”, suitable for solo playing.
A – the A bore is specifically designed for high note response, with some sacrifice for the lowest register.

Additionally, the two bores are available in one of three metal thicknesses:
D – German silver alloy; the D thickness is equal to the thin-walled Heckel bocals, of about .5mm average thickness. The thin wall allows for a lighter response especially in the lower register, and is the most flexible in tone color, with the possible sacrifice of some stability.
C – German silver alloy; the C thickness is equal to the standard thickness of Heckel bocals, of about .6mm average thickness. Well suited for players that don’t need anything out of the ordinary in terms of flexibility or projection.
XL – Germany silver alloy; these will be marked with the bore letter, followed by CXL, so CCXL or BCXL. This is the extra thick walled bocal, providing the most stability and power of the three thicknesses.
B – Brass alloy; these offer a more rounded and blending sound especially for a chamber music situation. These come in the standard thickness only.
S – Sterling silver alloy; offers a brighter sound. These also only come in the standard thickness.

We typically stock only the German silver alloy bocals in the C and B bores at the 1 or 2 standard lengths. Some limited selection of these bocals available in British bend as well!


  1. Hi Trent,
    I have two Puchner bocals from my 5xxx series bassoon. Shane Wieler has identified them as such. Shane told me that Puchner didn’t identify their bocals pre-1965. I’m guessing their lengths would be similar to Heckel. One is definitely thinner than the other. Was just wondering if you could offer any input. Many thanks.

I've only heard great reviews about this trial procedure with [Midwest Musical Imports, it was very convenient.
