What do yall consider typical problem notes on F tuba

[MaryAnn]

Actually, if I read correctly what the OP said, he has nailed what I think the "real problem" is with rotary F tubas. C and thereabouts slot pretty well if you're willing to play them a quarter tone sharp. It's only trying to make them play in tune, that makes them difficult, because that isn't where the tuba wants to play them. One friend of mine has lengthened his tuning slide by an appreciable amount and says that helps with the problem notes a lot. I'd be more likely to put on a gonga main slide kicker and try that, assuming there is main slide length available. Remembering that slide pulling is not for intonation but for centering.

The thing is, as stated earlier, many of us really like the rotary F sound which is why we are so willing to put up with this. But spot on, it's really only a few notes, usually that low C that needs to be altered to play well. Though, as said, this differs between horns.

Wade, my problem note, the worst one on my 180 is the low BBb in response (the one octave above is just sharp), I finger it 235, and just cant get it, the C is "fine" and can get a bite, same with the low A .....

235?

I finger my low Bb 4 5 and sometimes will whip out 1-4 if I need to.....235?
