The purchase of a cupronickel sax tube requires a certain ability to identify, we can identify the quality of the saxophone through observation:

First of all, it depends on whether the pipe body of the cupronickel sax pipe has any unevenness; whether there is paint peeling or poor copper, and whether there is a phenomenon of scribing and flowing paint.

Secondly, it depends on whether the tightness of the soundhole cover of the cupronickel sax tube is good and whether there is air leakage. The cupronickel sax has a good soundhole and its surroundings are even and flat and the fit is very good. When checking this part, we need to implant the lamp wire into the tube body or the bell mouth facing the direction of sunlight or sufficient light, and observe whether there is shimmering light.

Finally, check the imprint on each keypad of the cupronickel sax. Because the domestic mats are all pressed by the alcohol lamp after the test, because the skills of the workers are different, the effect will be different. Some imported musical instruments do not have this problem, because they all complete the whole cupronickel sax in the oven. Also, whether the reflector on the resonator of the cupronickel sax is in contact with the center of the soundhole accurately, and whether the keypad is tight. After tapping the cupronickel sax keypad, it is required not to leak air at all.

Through the above introduction and analysis of cupronickel sax, hope it helps you.
