The trombone models TB-350G und TB-450G are great for all around playing and provide excellent intonation, response and rich sound. In distinction from the TB-350G, which is made in traditional „closed wrap“-design, the TB-450G is a real „open wrap“ trombone. The TB-350G has a warm, compact sound, with its „open wrap“ design, the TB-450G sounds more open. The decision between the two instruments is a question of individual.
