The Jupiter JAS 500Q alto saxophone is a highly appreciated study instrument by students and teachers alike. Jupiter has managed to design a quality saxophone at an affordable price, ideal for music students. The right-hand keywork has been reworked and improved, making the mechanics of this robust instrument particularly smooth and pleasant. The low C#/Bb lever is more easily accessible thanks to this new design. The new springs make the keywork even more efficient and reliable.

Manufactured in Taiwan, this saxophone has a body, a neck, and mechanics in lacquered yellow brass. The thumb rest is adjustable in plastic for more comfort. The low C#/Bb rocker offers better ergonomics for musicians. The tempered steel springs allow for quick and precise action of all keys. The bell is detachable for easy instrument maintenance.

The Jupiter JAS 500Q alto saxophone comes with a mouthpiece, a ligature, and a mouthpiece cap for immediate use. It also comes with a Jupiter Light case for easy transport.

This Jupiter model is quickly catching up to its main rival, the Yamaha YAS 280. The homogeneous sound of this saxophone makes it a perfect choice for beginners, while the efficient keywork and ergonomics will suit more experienced musicians. However, the endurance and solidity of the keywork remain to be proven, as the JAS 500Q is a relatively new model. Finally, it is important to note that the weight of the JAS 500Q is slightly heavier than that of the Yamaha YAS 280, which may be a factor to consider for some musicians.
