The Jupiter 854L Deluxe Pro Double French Horn has been established as a respected world-class instrument. The Jupiter 854L Double Horn features a lacquered-brass body and Rose brass leadpipe for a focused, rich tone and tapered rotary valves with mechanical linkage for excellent action. The Jupiter 854L Deluxe F Horn includes a case and mouthpiece and comes in lacquer finish with a detachable screw bell (854L). In recent years, Jupiter's quality and consistency have skyrocketed as a result of hiring the world's best design engineers. Components are generated with incredible precision by computerized machinery so the highly trained craftspeople can concentrate almost entirely on exacting assembly and set up. All pads are hand-seated, all valves and tuning slides are hand-lapped, and all keys are hand-aligned and -adjusted. High-quality durable finishes are applied by hand, and each instrument is personally inspected and play-tested before leaving the factory.
