Thank you for viewing. Trumpet Jupiter JTR-300, Water Key Amado Key, Key B♭, ML bore 11.70mm, for beginners to experienced players. Pistons move smoothly without sticking. The 3rd trigger slides smoothly during playing. Amado key spit valve spring valve opens and closes normally. Good airtightness and a light, clear sound! The tubing has been pre-treated, the lacquer removed with solvent, and then stitch-processed and brushed up for an unlacquered satin finish (brass). This is not a satin-look paint spray. It has a dry and jazzy sound! No pitch deviation in the range. The appearance is cool, and performance will improve! It can be used in multiple situations! The semi-hard case is a genuine Jupiter upper-class case, a rare case that is not often seen. It is slightly heavier than a general semi-hard case, but it is a sturdy and robust case. JUPITER's professional series starts with the 1100, and the appeal of JUPITER is that you'll want even higher-end models like XO. This case also has excellent holding ability! It can also be used as a backpack, making it convenient for travel. The Velcro, zippers, and handle case body are in good condition without any problems! A new, unused gold mega mouthpiece, non-manufacturer 7C standard size! After soaking in baking soda and citric acid for 2 days, the inside of the tubing was brushed, and then washed with neutral detergent to remove dirt, verdigris, and mold, making it hygienic and ready to play upon arrival. JUPITER, made in Taiwan, is so good that you'll get hooked once you play it! Please consider this opportunity.
