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!
