An amateur confronts his instrument
What kind of bassoon is that?
How do you get on with the C sharp/A rollers? Worth having?
The tenor joint rollers are between C# and the whisper key. It's kind of a confusing pic, as my horn has another key below the whisper key, which is for the ratcheting whisper lock. There's no roller on the A. The C#/whisper rollers are good, I like them. Some people go crazy with rollers, but that spreads the keys out, since the rollers need room. My right thumb cluster uses single sided rollers: a roller on the Bb and F#, but none on the E. The ratcheting whisper lock I wouldn't recommend. It's noisy, can go out of adjustment, and needs to be depressed quite far, which detracts from the supposed ease and speed advantage. But it does work.
I see low c#-d# trill key beside low C keyI'm guessing that it's FOX bassoon.
