JupiterJEP1120 Performance Series Compensating Euphonium JEP1120 Lacquer
Independent shopping perspective
The Korena take
Jupiter’s JEP1120 is a Bb compensating euphonium with a 3+1 valve layout: three top-action valves and one operated by the left hand. Its graduated .590–.660-inch bore leads to a 12.2-inch upright yellow-brass bell. A rose-brass leadpipe and rose-brass tuning-slide crooks provide a distinct visual contrast, while stainless-steel pistons form the valve system. The instrument is described for solo work and blending with other brass, and it comes in an ABS molded case.
Strong match
Who this is for
- Solo passages requiring the euphonium’s described tonal color and complex harmonic content.
- Brass ensemble playing where the instrument is described as blending with other brass.
