Compensating 3+1 valve configuration for spot-on intonation

The Jupiter JEP1120 comes complete with a fully-compensating 3+1 valve configuration. This welcomed addition makes low-register playing more straightforward than ever before. The compensating system enables your JEP1120 to play with spot-on intonation throughout the instrument’s entire range. What’s more, this euphonium ships with ultra-durable stainless steel pistons that last through years and years of wear and tear. If you’re looking for a value-packed compensating euphonium, you’ve found it with the Jupiter JEP1120 3+1 Valve Professional Compensating Euphonium.

Stress-free assembly improves performance

Jupiter uses a unique construction and assembly process to relieve stress within the instrument’s tubing. This construction method reduces stress within the instrument’s tubing and solder joints, leading to improved performance and an overall increase in sonic clarity. The JEP1120’s stress-relieved construction, combined with the yellow brass body and expressive bell, delivers a warm and resonant tone fit for high-performance applications. Audition the JEP1120 for yourself to hear the difference!
