Jupiter 1100 Performance Series JAS1100Q Alto Saxophone

The Jupiter 1100 Performance Series JAS1100Q is a beautifully crafted alto saxophone that combines traditional workmanship with modern innovation, making it an excellent choice for advancing students and gigging professionals alike.

At its heart is the Sona-Pure neck, forged using artisan tooling and an annealing process to deliver a warm, vintage tonal character. This neck mates with a gold-lacquered brass body and keys, producing a rich, resonant sound that is both reliable and expressive.

The saxophone’s mechanical design is equally impressive. Ergonomically optimized keywork — including adjustable palm keys and a metal thumb rest — ensures comfortable playability over long sessions, reducing hand fatigue and enhancing technical fluidity. Its High F# auxiliary key, tilting C#–Bb rocker, and adjustable upper/lower stack screws help fine-tune and stabilize your play.

Durability is built into every detail: blued-steel springs provide responsive, resilient action, while metal tone boosters on the pads not only boost projection, but also help ensure a tighter seal for better articulation. The adjustment screw for the body-octave key offers reliable middle-A tuning, a thoughtful touch for players who demand consistency.

To complete this premium package, the JAS1100Q comes with a lightweight but sturdy.

Why It Stands Out

• Tonal Versatility: The Sona-Pure neck and gold-lacquered body combine to produce a warm, balanced tone with strong projection — ideal for both classical and contemporary settings.
• Ergonomic Comfort: Its adjustable keys and thumb rest make it highly customizable, which means less strain, especially during long rehearsals or performances.
• Reliability and Build Quality: With quality materials, robust springs, and precision-engineered mechanics, this sax is built to last and perform.
• Professional Features at the Right Level: High F# key, tuning adjustment, and ergonomic upgrades give you features that are often reserved for more expensive pro-model horns — all in a performance-level instrument.

Who It’s For

• Intermediate to advanced students ready to make the leap to a more professional-quality horn
• Performing artists, band members, and gigging musicians who need reliability and expressive tonal control
• Saxophonists who value ergonomics and want a well-balanced instrument that adapts to their playing style
