Combining John Packer’s manufacturing expertise with design input from renowned UK trombone specialist Michael Rath, this instrument delivers excellent response, powerful projection and professional-level playability.
Ideal for orchestral sections, brass bands and big band performance, the JP332 Rath offers the versatility and tonal depth required as players advance into more demanding repertoire. Its carefully balanced construction and ergonomic design help developing musicians perform confidently while supporting strong technical development.
With a build quality often compared to professional instruments, the JP332 Rath provides exceptional value while offering performance features typically found on higher-level models.
The JP332 Rath features a specially designed Rath leadpipe, created to deliver excellent response across all registers. This carefully engineered design helps players achieve a centred tone with reliable airflow and strong projection, while still providing support for those refining their technique. The result is a flexible instrument capable of handling a wide range of musical styles and performance settings.
With a large .547" bore and an 8.5" bell, the JP332 Rath produces a full, rich sound suited to symphonic repertoire and large ensemble playing. The bell construction, using high-grade 80:20 brass, enhances tonal warmth and projection, allowing players to blend effectively within orchestral, brass band and jazz environments.
The larger bell size provides increased depth and presence compared to smaller tenor trombone models, supporting confident performance in lower dynamic ranges as well as powerful climactic passages.
The Bb/F configuration with rotary valve provides extended lower register capability and improved technical flexibility. The closed-wrap F attachment design helps maintain comfortable balance while supporting efficient airflow through the instrument.
An adjustable ergonomic thumb lever allows players to customise positioning for comfort and control, particularly beneficial for younger players or those developing hand strength. The inclusion of a counterweight further enhances overall balance, reducing strain during extended rehearsals and performances.
Constructed from high-grade brass throughout, the JP332 Rath is built to withstand the demands of regular rehearsal, performance and educational use. The instrument is supplied in a traditional lacquer finish, providing durability and visual appeal.
Two water keys allow for efficient moisture management, helping maintain consistent playing performance and instrument longevity.
