Hi, I recently purchased a new Yamaha 62II alto saxophone, and I'm having some trouble with the bell keys. I brought it home and noticed that the C# key lifted with a sort of "bounce", and that the large gap from the Bb to B (and vice versa) made making smooth transitions between the two notes very difficult. I then brought it in a few days later to have the C# key looked at along with to see if anything could be adjusted on the Bb/B keys. The man told me that he increased the spring tension on the C# key and adjusted the spatula keys a bit. After returning home and inspecting the instrument again, I noticed that when pressing the Bb key, the Bb and B keys do not completely cover their holes (very, very small gap on the Bb and a slightly larger gap on the B). This is also the same when pressing the low B key. When substantial strength is used, however, (and the right area of the key is pressed) the keys will cover the holes completely. I also noticed that when both the C#/Bb keys are pressed at the same time, smalls gaps open on the B and C# keys, should this be happening? Does anyone have any idea what could be the cause of these problems? Thank you!
