Example of some bassoon keywork customization from our repair shop

February 24th, 2015 by

Bassoon specialist Trent Jacobs has his bassoon further customized by our head repair tech Eric Anderson. Check the description and photos on his blog.

After careful consideration, I decided I wanted to add a right hand Eb trill and offset the C# trill on my bassoon. I had Eric Anderson at Midwest Musical Imports again do the work. We used Fox key castings and posts and had the plating done at Brinkman’s Silver Plating in St. Paul. Some components, as always had to be made specifically for these keys. Here’s a gallery of the entire process!


  1. I’d like to have some modifications done on my vintage Linton bassoon, which I had completely restored last year. I’d like to add High D and E keys, an Ab/Bb trill and a left-hand whisper key lock. Would your shop be interested in taking this project on? If so, a rough estimate?

  2. Steve, I just replied to another customer requesting similar options. In short, the addition of the tone holes is beyond what our shop is set up to do.

  3. I’m looking into having some additions done to my Fox 220 – Ab/Bb trill, D-Eb trill, high F, left hand whisper lock. any estimate of how much this may cost or there may be any issues with such additions? thanks

  4. All three of the extra trill keys will require new tone holes in your instrument. Our shop is not set up to do this work. Building the keys for alternate touches as in the description is not quite as involved, however you are looking at re-building the Bb mechanism to add the Ab/Bb trill key, and re-building the high Eb/E keys for the high F addition. It is not as simple as adding just a single key to the bassoon.

    There are some other technicians that may be able to do this work for you, however if you need these keys you are ready to step out of your 220 into a professional instrument. Fox will not put any of your requests on your instrument. My rough guess as to what a good bassoon tech would charge for this work (if they will do it on a 220) is $3000-4000 if you get the new mechanism silver plated. It is significantly less to have the manufacturer (at least with Fox) put these keys on a new instrument in production.

    We typically order our stock Fox model 680 bassoons with your requests, minus the left hand whisper lock. The Puchner model 5000 bassoons come with the trill keys but the high F would be an add-on option.
