The JP233 RATH is John Packer's Bb/F Single Valve Bass Trombone, developed in collaboration with UK trombone guru Michael Rath. This JP Rath design combines the simplicity of a single in-line rotary valve with a modern open wrap style. The development of the JP233 RATH saw the instrument finely balanced to ensure an excellent playing experience for musicians of all levels. An extremely high level of craftsmanship is apparent throughout, as is to be expected with instruments that bare the Rath seal of approval. The quality of the JP233 Rath has caused a real stir in the industry with glowing reviews from many top players. Garreth Beckwith formerly of Grimethorpe Band recently described it as "a real winner of an instrument" (See Gareth's full review and others below).

The JP233 Rath features a .562" bore and a 9.5" bell and is constructed from yellow brass throughout. The instrument also features an exclusive Michael Rath design leadpipe which supports flexibility throughout the whole register.

The JP233 RATH Bb/F Trombone is supplied with a JP mouthpiece and lightweight case. The case is well designed to be robust yet lightweight and to provide as much protection to your instrument as possible. It is equipped with backpack straps and a comfortable should strap as standard and also includes a small storage pocket accessible from the outside suitable for storing small accessories and sheetmusic.

Manufactured to a high quality standard as is expected with all JP Instruments, the JP233 RATH Bb/F Trombone is guaranteed for 12 months against faulty manufacturing or materials and is fully tested prior to sale.
