Jupiter is a relatively new entry into the world of professional model instruments, and as a trombone player I must say I'm pretty impressed. These horns play very nicely with a dark tone quality and excellent response. This horn has a nice open trigger register and this horn plays very nice. Factor in the attractive price point and you have a winner!

Warranty coverage does not include damage from accident, misuse, negligence, improper operation, unauthorized alterations or removed serial numbers, normal wear and routine maintenance, environmental damage (including perspiration, corrosion, or extreme temperature and humidity), lacquer or plating wear, or consumable parts such as springs, pads, and felts. Please see our FAQ for additional details.
