The Jupiter JTR710S is a pocket trumpet with a compact design and a great sound. Thanks to the large bell with a diameter of 123 mm, the JTR710S does not sound as bright as many other pocket trumpets. Its low weight makes it a perfect companion when travelling. Even children who are still too small for a normal Bb trumpet can take their first steps in the world of brass music with the Jupiter JTR710S with good intonation and easy response. The valves made of stainless steel are robust and smooth-running.
