John Packer 'JP333' Bb/F/Gb Bass Trombone | Lacquer | NEW

The John Packer JP333 Rath Bass Trombone is a double-valve bass trombone developed in collaboration with Michael Rath, one of the UK?s leading trombone designers. Built for a broad, free-blowing sound, the JP333 features a large .562" bore, a 9.5" bell, high-grade brass construction, an in-line rotary valve system, a modern open-wrap design, and a custom Michael Rath-designed leadpipe that supports flexibility and response throughout the full register.

This is a strong choice for bass trombonists playing in orchestras, brass bands, concert bands, trombone choirs, and big band sections. The double-valve setup gives players expanded low-register options and alternate positions, while the counterweight helps balance the instrument for a more comfortable playing experience. The JP333 is especially well suited for advancing students, serious community players, and developing bass trombonists who want a capable bass trombone with professional design influence at a more accessible price point.

New John Packer instruments include a 2-year manufacturer warranty against defects in materials and workmanship from the original date of purchase.
