The first sax I bought was a Prelude AS700 a few months ago,
Recently I purchased a secondhand Yamaha YAS-23 after spotting one at a couldn't reist price 🙂 .
All notes were good and I liked the feel of the mechanism/keys far better than the prelude. Everything was ok for the first couple of weeks.
Then the high octave notes started to warble, especially high E, F and D were not as bad. With the noise it seems as though it was oscillating between octaves. I first blamed myself , as a beginner it had to be my embouchure, I could just about stop it with more biting pressure but this was not the answer. Tried different reeds with no solution.
Then I took mouthpiece and reed and placed it on my Prelude, high notes played perfectly .
So back looking for a solution, after surfing the many topics in the forum it pointed to the octave body hole. Saw one suggestion of drilling it slightly larger. Not wanting to start with such major operations I closely inspected how the mechanism worked. The body octave pad wasn't lifting very high.
I straightened the vertical pin that connects with the top arm first, then I bent the upper arm so that the crook pad closed with only a small clearance left between the pin and arm. Then I reduced the thickness of the cork pad which altered the resting position of the pin arm. This gave a greater lift to the body octave pad when the g key is pressed and hence a larger clearance over the tone hole.
This cured my problem, All high octave notes now play with ease.
One extra adjustment I also made was the screw above the F pad so that the Bis key had no free play .
Heres hoping I did the correct fix and if you all agree perhaps it will help other beginners if they experience a warble on High E.
Thanks for all the info posted here, it sure helps,
Rod.
