Today during my practice I thought, "I wonder if that plastic bell protector around the rim can have an effect?" It was a fitted very tight which is why I have never removed, knowing I would be unlikely to get back on if I took off and really needing for marching gigs where obviously I do not have a stand to put it down.
However, I decided to take the risk and remove the rim for the first time. I could not believe the difference - it has now got the ring and provides the vibration feedback I get from my PT-15 and Neptune - it is like a different tuba - feeling MUCH BETTER and more responsive
I will now cut the bell rim band and just put on 'loose' when needed.
