When I press the G sharp key on my VR alto the low B pad on the bell flops closed. When I press the low B key, the pad on the bell closes and opens correctly. Doesn't happen on my Big Bell alto and I Just noticed it today. Looked for a spring knocked loose but everything "seems" to be in place. Anything I can look for or should I take it to my sax repair guy? Any help will be greatly appreciated. I hope I verbalized this enough to make sense.
