An incredible flugel, I know a lot of pro trumpet players who have chosen Jupiter for their flugel because of the combination of playability and price. The 1646 flugelhorn has a special bore and bell taper to produce a classic rich, warm timbre desired by professional brass players of any musical style. A solid nickel silver tunable leadpipe enhances the tonal focus and creates an incredibly rich tone. Great valve action, third slide kicker, and the rose brass bell really warms up the sound.
