Topic: Sticky bocal
I have this bocal that I really like, and use a lot for my jazz/electric playing. It's an unplated brass bocal made by Guntram Wolf. I used this a lot with my Wolf bassoon and had this issue where the whisper key would stick to the vent nub on the bocal. I always thought it was the pad on that bassoon. For the last 5 years I've been using a Moosmann bocal with my Moosmann bassoon, but started using this Wolf bocal for my jazz playing like I said, and found that it's started to stick again. So this leads me to think that it's the bocal and not the pad, since it's a different bassoon.
The pad does need to be replaced as it's showing some wear, but it seems like the bocal causes this issue. Is there a reason that this might be happening? Might moisture be getting through the whisper hole/nub? The bocal recently saw some maintenance from Marvin Krantz, and he cleaned the thing so that it looked like a gold plated bocal, so I don't think it's an issue with the outside of the bocal... might there be debris in the nub that causes moisture? Any other likely causes to this?
I have other whisper key related issues that need to be resolved, but this is one that is bugging me... Cigarette paper seems to be a temporary solution, but I don't have this issue with other bocals that I've noticed.
Any pointers are welcome.
