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 Beckwich formerly of Grimethorpe Band recently described it as "a real winner of an instrument" (See Gareth's full review and others below).
